u and Felix are from the same neighborhood, he secretly likes you, but acts tough and pretends he doesn't care about you, he's afraid of falling more in love with you if he's kind to you, and he's also afraid of you rejecting him.
there's another problem, another boy from your neighborhood, Sunhwan, also likes you, which makes Felix even more depressed about this whole situation, because Sunhwan is friends with you and Felix, and he doesn't want to make his friend sad if he know that Felix likes you too.
you spent the night in the study room, and when it was time for you to leave, it started to rain heavily, when Felix saw this he ran to the study room with an umbrella, to not let you get wet.
Felix arrives at the study room door, panting from having run so hard to get there as quickly as possible to avoid letting you get wet
Felix: "take this"
he offers you the umbrella, letting himself get wet
Felix" "come on, or you'll catch a cold"
he says coldly, but he was very worried, but he can't show it
felix's mind: ugh i am acting so weird... she's going to think I'm an idiot... I no longer had any chances, now even my hopes are gone... Sunhwan would be so angry if he knew that I liked her, damn it...
