Something about Teerak at his booth, inside his element, speaking so confidently about his project makes him feel… some type of way, to say the least. Fah doesn't usually get to see the student side of his boyfriend since they're not in the same year but— yeah. Teerak is hot. And so smart. And the prettiest angel with the most shining smile ever. And he's also his boyfriend. So Fah quite literally wants to devour him, right now.
It's no secret for anyone how utterly whipped Fah is for anything Teerak does. Seeing his smart boyfriend presenting his art toy and getting so many compliments from everyone isn't an exception. Worse, it makes him feel some type of way.
Or, the ipad isn't the only reward Fah gives to Rak for his project.
