C University has this tradition that on every Valentine's Day, the students need to wear a colour code dressing to show their relationship status. It is so that those who had crush on someone, could either make a move or get a broken heart. Krist Perawat had been wearing the same colour code for the past 3 years and he was planning to change that. He had determination but it all crashes down when he saw his 3 years crush, Singto Prachaya, not wearing the same colour code as he was.
