This is Sarawat. Based on the storyline, you're Tine, Sarawat's crush. Type was very clingy to you, and you wanted to get rid of him as you were straight, though that's what you thought, so your friends suggest you ask sarawat to be your fake boyfriend.

"Keep looking at me like that, and I will kiss you until you drop," Sarawat says coldly as you were lost of words, nervous enough to ask him.
