Why You… Y Me? - Season 1

Gap's band performance is interrupted by a squad of fan girls, but an opportunity arises later when he meets Namwah, one of the organizers of the fans. Not only does Namwah's family own a studio, but her brother Shogun is a well respected producer that Gap and his bandmates would love to meet. 

Namwah and Kanoon went to a movie premiere where Copter played a lead character. Maipai was also here at the event. However, Namwah and Kanoon struggled to find entry tickets. They met Gap who held VIP tickets to the same theatre as Maipai. Gap broke a deal, asking Namwah to bring P'Shogun to help Evening Sunday compete in MOM. Namwah quickly accepted the deal. After the movie ends, all three were interviewed by reporters about the movie. Namwah gave an interview at the same time Star did. Both had an argument and the topic shifted to MOM where both have their own band competing in it. Star mocked how Namwah will never find a good band to compete with. Gap was displeased after hearing that, saying they are not incompetent. The reporters shifted their attention to Gap and asked him more questions. At one point, Gap spilled out saying he is a fanboy of Copter and Maipai. That extremely excited Namwah.

Namwa suggested that Evening Sunday should do a proper video of their performance to send to the contest and she will help promote and do the production. Namwa brought all of them to do live session at a lighthouse which located in the middle of Andaman sea. In order to get to the lighthouse, they need to get on the train, a ferry and then a minibus. A lot of obstacles occured on the way ; having no power outlet for their equipments at the lighthouse, and Namwa dropped the camera into the ocean. Despite all that, the production went well because of Gap. This made Namwa so impressed for what Gap has done for them and without knowing Namwa starts to develop special feelings for Gap. Meanwhile, Maito started to be trembling with Shokun, it was so obvious that Green could notice. Paul and Nice began to open their minds to each other.

After coming back from filming, Namwa went to see Gap at his place to ask about how to recover the broken memory card. Gap didn't know she was coming and he almost got caught that he had Maipai as his roommate. Namwa walked into Gap's room and found out he had a lot of Maipai rare items which she really thought Gap must be a big fan of Maipai. On the next day, the band started editing their live session video. Suddenly, they realized they hadn't recorded the actual song yet. So, they went to see Shokun at the studio. Namwa and Gap had a mission at the grand opening of Phenomenal Perfume which Copter was a presenter. In the event, Namwa and Star were competing to win the activity of the event. At the end, Star won but Namwa noticed that the sweater Star was wearing looked similar to the sasaeng that sneakily stalked and took photos of CopterMaipai. And she decided to dig deep into this along with Gap.

Namwa and Gap took a win for their report project and they had to set up a booth in Thai and Global population exhibition. In the meantime, Evening Sunday had paul to finish editing their live session video. But when they uploaded it on internet, nobody watched it. Everyone was about to give up but Shokun motivated them to practise more. Piak told Shokun to pick up what he ordered by himself because he wouldn't be available, therefore Maito offered to help. Namwa was in the middle of setting up the booth but she didn't see Gap at all. She started getting worried, so she went to check on Gap at his house. Then, she saw that Gap was fighting with his dad and that almost got him withdraw from MOM contest.

The audiences started criticizing and getting disappointed. Ford was pissed off when he came down from the stage. Everyone in the band fought and went their several ways. Maito went to see Shokun and confessed to him.

Namwa went to Gap's room to get his earphone and she found out that Maipai was his roommate. Namwa was extremely mad that she had been fooled all this time. And Ford was also angry at everyone for not working hard. Then, he left the group chat of Evening Sunday. Everyone went to see Ford to reconcile and asked him to come back agin. They all went to apologize to Shokun and they promised that they would work hard and wouldn't be off the track. At the studio, Maito tried to hide from Shokun because he was rejected.
