Oh! My Sunshine Night

Kimhan performs on stage in a cello audition competition for a world contest. He wins the audition and becomes a Thai cellist representative. When Kim gets back to the music club, he found Sun practicing in the auditorium. Their first encounter doesn’t end up well when Kim accidentally steps on Sun’s finger, and Kim storms out the room. Meen has been looking for Kim to congratulate him on his win but ends up fighting. While Meen is bashing Kim, Sun unexpectedly observes the incident. Kim also notices that Sun is there, and that makes Sun fidgeting because Sun doesn’t want to be nosy. It turns out that Kim doesn’t think like that, so Sun wants to make friend with this unemotional new friend, leading to stories to be told.

Kim and Rain grew up in a family that demands them to take over the family business. Rain, the older brother, is expected to be an heir by his father while Kim is always being compared to his older brother. Every time Kim is hard-pressed, he always retreats to his safe zone which is in the water and his garden. At the same time, it’s Sun’s birthday, but there’s only an automatic message that wishes him happy birthday. Therefore, even though he lives in a big and crowded city, Sun feels lonely in his room.

Sun tries hard to join the band. Prof. Wannasingh sees Sun’s enthusiasm, so he lets Sun observe the band rehearsal. While the band is rehearsing, Sun suddenly has heart symptoms and notices that his bag is torn. All apples that he brought with him to soothe the symptom fell through the bag’s hole. However, Kim also notices that Sun’s bag is torn and knows that Sun needs those apples. What should Kim do when a friend who helped him is in trouble now?

Sun invites Rain to join the Fraternity and Sorority meeting. When Rain meets Sun, he is struck by Sun's friendliness and has the idea of wanting Sun to become friends with Kim. Without further ado, Rain wants Sun to change Kim’s personality to know how to make friends and socialize. After the meeting, Sun drank. Baibua asks Kim to take Sun to the condo because Baibua knows that Kim is the only person who knows about Sun's Condo.

After school, Kim notices Sun begin to relapse again. Sun hurries to find a place to hide so that no one can see. But Kim follows and sits beside a friend. Rain comes to see Payu and takes care of him, but Baibua accidentally sees Rain helping to wear a shirt. In the evening, Kim receives Pie's invitation to meet up at a café near the university, but Sun and Chun go there too. While Petch and Oh also follow Pie as well. So the chaos occurs.

Kim dives in to recall childhood memories that always make him smile and happy when he remembers that memory. At University, Rain lets Payu cool down simultaneously; Baibua brings Payu stuff and sees the moment while Rain and Payu are cooling down for each other. At the music club, Prof. Wannasingh called an urgent meeting about the classical guitarist who had an accident. As a result, the music club had to cancel the show at the closing of the ruby ceremony. Meanwhile, Sun accidentally enters the music club room. And something happens.

Pie brings Kim home, and Pie realizes that Kim has no idea about him. Kim notices Petch sends Sun to the music club. Kim is frustrated when witnessing the incident, which causes the group's rehearsal not to go smoothly. Prof. Wanasingh gives them a separate practice. But Kim and Sun are tense. And there is an argument, so they do not practice together, but there is Rain, who comes to help as a practice partner for Sun. After the rehearsal, Kim walks over to see Petch and Pie clearing up while Sun follows suit. Kim thought that Sun might like Petch. So Kim tries to prevent Sun from witnessing the significant incident.

After the music rehearsal finished, Kim sends Sun to the condo and invites Sun to go for a walk. They both talk and open up more. Meanwhile, Shun tries to approach Rain to win Rain's heart. Then, the university's rugby event kicks off. The music club has been working hard to perform at the closing ceremony. And at the closing ceremony, the club's band started playing.

After Shun, loyal to his heart, continued to approach Rain, but Rain himself tried to follow his heart. Phayu returns from an extra job and comes across Rain, who is wet from a diving competition with Kim. Rain asks Phayu to wipe away and try to find a way to bring Phayu closer together. It's time for a camp event organized by the pre-semester music club. Kim Sun and friends from various music clubs also joined. So the fun and chaos are about to begin again.

At the camp of the music club, there are various activities to play games to create fun and make everyone who participates in games get to know and get to know each other better. For example, while playing the matchmaking game, Sun has a heart attack, but Kim and his friends help Sun. And that night, Chun decided to kiss Rain but didn't get the kiss. Instead, Rain remained silent. Rain also saw that Chun was brave enough, to be honest with his heart, so he decided to do some Phayu until the two had cleared their minds. Kim and Sun also seem more open-minded from the camp at sea.

Kim and Sun meet as the semester break approaches while clearing up the staff. Kim had already collected all the subjects. Even Baibua decided to clear her mind with Phayu at the grill shop. Rain and his family had already reached the villa in the middle of the valley. And after Kim and Sun finish packing at the university, Kim sends Sun to the condo and gets up to the Sun condo again.

On the morning of the semester break, Kim and Sun meet in front of Sun's condo and invited each other to go shopping at the supermarket and cook food at the condo with Petch and Pai. Kim is also allergic to shrimp in his diet and sleeps at Sun's condo. So both spend more time together, and good feelings also started to build up. Rain, the Kannakul family, and Dr. Sukhwan, a business partner, have agreed to purchase a safe house in the middle of the valley and are on their way back. The business that Rain will continue from the Kannakul Group and the beginning of the relationship between Kim and Sun is like a blooming flower.

An unexpected incident happened to the Kannakul family during a helicopter and motorbike crash; amid the loneliness of Kim, who lost his parents and no trace of his brother, Rain. In this atrocity, enough light and strength from Sun would give Kim a heart to cry for him. And there's also a peace butler and a storm to watch over. But all these bad things seem to be no ordinary accidents; the search for the truth and the chase occurred.

Phayu takes Kim to live at Safehouse in Chengrai. While Santi is trying to investigate Dr Sukwan closely. Sun and all their friends are finding Kim everywhere, but nothing. Then, three months later, Kim loses his memory gradually from the last injury. No one knows what will happen next.

Friends try to contact Sun, who has disappeared. Kim spends time recovering and hiding from Dr. Sukhwan's hunting at a safe house in the middle of the valley under Phayu conditions and receiving regular medication. However, some of Kim's memories seem to have faded. Phayu tries to find a cure for Kim and thinks Sun is the best way to help Kim's memory back.

Sun and Kim's friends arrive at a safe house in the middle of the valley from Phayu's persuasion to help Kim's memory improve upon a doctor's recommendation. Sun spends time talking with Kim and trying to get Kim to remember the past. Coming to the safe house this time, Everyone spends their time together, especially Petch and Pie, who have cleared their minds and understand each other. Meanwhile, Dr. Sukhwan proceeds with business interests and thoroughly pursues the Kannakul brothers. Butler Santi is continuing to investigate and defend the interests of the Kannakul family with all his might.

At a villa in the middle of the valley, Sun uses music to help bring back Kim's memories, and the day the star lovers meet. Everyone prays for what they want, while Sun does everything he can to bring back Kim's memory. Meanwhile, Kim tries to get all his friends out of the villa as quickly as possible.
