En of Love

Gun, a popular first-year medical student, secretly admires Bar, his senior from high school, now a third-year engineering student. One day, Gun picks up an accessory that symbolizes being an engineering student and uses this opportunity to get closer to Bar.

A week after starting to pursue Bar, Gun surprises him with a small anniversary gift. Although Bar acts cool around his friends who tease him, he doesn’t seem entirely displeased with Gun’s persistent affection.

While Gun and Bar are at a bookstore, they encounter first-year engineering student Mark and first-year business student James. Mark, who likes Bar, openly flirts with him, leading to tension between him and Gun.

Gun and Bar’s morning together is interrupted by Beam’s unexpected visit. Turning down Beam’s invitation, the two decide to go out for breakfast. Bar’s unusually affectionate behavior leaves Gun blushing.

Heartbroken over Bar, Mark gets drunk at a club and mistakes senior engineering student Wee for Bar. He drunkenly flirts with him, and a concerned Wee ends up taking care of the unstable Mark. The next morning, they wake up together...

Ploy returns home in the morning, claiming she stayed over at a friend’s. Wee, who knows she was with another guy, goes to Mark’s room with mixed feelings. When Wee asks to stay over, Mark lets him in.

At the Wink Bar where he was supposed to meet Wee, Mark sees Wee kissing Ploy and leaves in shock. Wee tries to follow, but their friends hold him back.

While eating with friends, Mark receives an emotionally direct message from Wee. Later, when everyone is studying in Mark’s room, Wee comes by and invites him to watch a soccer match together...

Wee’s friend, Nua from the engineering faculty, instantly falls for high schooler Praram at a party. Though his friends tease him about moving on quickly from Mark, Nua is serious about his feelings this time.

Gun, protective of his younger brother, warns Nua, who has a reputation for being a playboy. Nua’s friends joke that to win the younger brother, he needs to win over the older one first. Nua keeps texting Praram, eagerly awaiting a reply.

Praram studies for exams with his seniors and twin brother Prarak. Nua’s sweet and persistent affection for Praram becomes a hot topic among the group, but Gun is visibly displeased with the growing closeness.
