Season 1 - Love Puzzle

With a close friend, Pleng goes to Bangkok to further his studies. On the night of their arrival, Pleng and his friend go out together and meet a stranger who challenges them to a game of snooker, wagering with alcohol. Pleng gets swindled and downs glass after glass. Infatuated with this stranger, Pleng ends up in a hotel room with the guy. In the morning, though, the stranger is nowhere to be found and he's paid Pleng back for the alcohol entirely.

On the day of the Faculty of Engineering's initiation, Pleng is stunned to see the stranger he spent the night with is a senior name Prai. Prai is cold. Here begins the process of hitting on his senior with the help of his friends and seniors of various faculties.
