WHAT TO DO WHEN SOMEONE CONFESSED?!

Hi, my name is Vien, 17 and no boyfriend since birth (but I had some mutual understandings), so this evening as I was watching YouTube on my tablet I received a text message from my classmate, well me as their president I'm used to these situations where they ask some questions and stuffs, this particular classmate said something that made me think that "oh shit, I know what's going to happen" becausee he said that "Wait, let me breathe for a second" THAT'S THE LINE OKAY?? OF COURSE I'LL GET SUSPICIOUS AND GUESS WHAT?! I'M RIGHT Look, I've never EVER received a confession from a classmate before T^T and if I do know that someone likes me I'll immediately turn a blind eye because it's just uncomfy around the people who actually likes you, and I'm boyish okay?! I don't even know what they liked about me, this time around I was thinking of just letting him wait for a response and tomorrow I'll just say that I didn't see message because of the group chats. I've already let down some guys at my school but those aren't my classmates and plus I have a type okay?! (⁠ ⁠≧⁠Д⁠≦⁠) I just don't know how to handle this thing right now I like romance, but I can't see myself actually partaking it.
