On his first day he is also rescued by stranger who helps him fend off an attack from a group of thieves. Pai later learns this stranger is Itt, the president of the sports club. Their first official meeting is quickly soured when Pai and Itt learn their clubs must share the same space for the year. Itt is a handsome engineering student who is an ex-president of his school's sports club. He has always been in a spotlight. Fate brings him back to his enemy who always wears a dust grey medical gown earring.

After a quarrelling Waan and Pure are caught with a broken Projector at their feet, Waan makes a discovery that moves him to take the blame for the damage Pure caused. Only their teacher knows who was truly to blame and decides to use her position to force Pai to tutor Itt. Pai chases the opportunity to improve Itt while Itt does his best to dodge him. Itt is a handsome engineering student who is an ex-president of his school's sports club. He has always been in a spotlight. Fate brings him back to his enemy who always wears a dust grey medical gown earring.

As Pai tutors Itt, the adversaries are swift to form a friendship that goes beyond schoolwork. Itt feels empowered to pursue Engineering and Pai feels empowered to make mature decisions for himself. At school, Pure invites Waan to play basketball with him and the two develop an amicable relationship. Pure has Waan's attention now.

When Waan fails to implement Pure's flirtation techniques at the cafe and gain his crush's attention, Pure takes Waan to a club to drink and hopefully more. Pai's recent distance from him is hurting Itt.

Itt and Pure have stopped going to school and Waan and Pai seem to be the only ones concerned. Waan goes to find Pure who's holed up in his room and Pai goes through Itt's girlfriend Pang to find him.

Itt, Pai, Waan and Pure nurse their budding friendship. Pai is willing to double his time spent tutoring Itt in an effort to secure his friend's future.

After he overhears a private conversation between Pai and their teacher, Itt feels their friendship is over. He punishes Pai by leaving their clubroom, depriving Pai of his treasured earring and firmly rejecting any of Pai's attempts at kindness. Folk clumsily makes himself known to Pai and Pure in turn.

Pai and Waan have begun their first term of University. Pai doesn't remember Folk, who quickly makes his interest in Pai known, and he's entirely unprepared to encounter Itt, who's found new ways to punish him.

Pai struggles to perform the confidence he'll need to win the contest. Waan pursues Beau, Folk pursues Pai, Pure pursues everyone, and Itt seems to have more complicated feelings than he lets on.

Pure and Folk agree to be friends with benefits. Waan is troubled to see Pure getting close to Beau. Itt and Pai continue to be at odds with one another.

Pure and Waan clear up some misunderstandings and start new relationships. Pai learns the truth about Mr. 950.

Pai's parents are shocked when they discover that Itt and Pai have a romantic relationship. Despite all that Pai has learned about confidence with Itt's help, he still struggles to express him needs fully to his parents.
