Perfect 10 Liners

As Arm enters university, he is introduced to his peer mentor group, the Perfect 10 Liners. He unintentionally gets off on the wrong foot with his senior, Arc, after posting his photo on the Engineer Cute Boy page.

Arc makes an attempt to spend more time with Arm, but his teasing attitude leaves Arm unsure of his intentions.

Arc shows a different side of himself after the car accident. As Arm's pinning ceremony approaches, Arc encourages Arm to make more of an effort to get to know him more.

Arc and Arm take turns caring for each other as Arc gets injured playing soccer and Arm finds himself in the middle of a bar fight.

Arc and Arm take a trip together to get his bracelet from one of the founding member of his mentorship group.

Arc confesses his feelings but Arm asks for more time to reflect on how he feels. However, Arm starts to feel possessive when Arc's buddy Brink makes an appearance.

Arc finds himself competing with Arm's new "buddy", Tongfah, who appears to be endlessly charming and talented.

Arc and Arm say goodbye to their buddies. Arc gifts Arm his engineering jacket, but Arm loses it after wearing it for just one day.

As the new school year starts, the Perfect 10 Liners meet their newest mentee, Yotha. Yotha's brother Faifa makes fast friends with fellow freshmen, Gun.
