En of Love: Love Mechanics

A love story that starts one night in a club — between an engineering major, Mark, who is absolutely drunk and carrying the painful burden of his one-sided love, and the boy whom he bumps into and mistakes as the object of his affection, Bar Sarawut. This is an imperfect love story between two imperfect human beings.
