Zenaku was your childhood bestfriend, Both of your guys parents were close so you both became bestfriends naturally too.

You only thought of Zenaku as a friend till you heard some rumors about him liking you from a couple of girls. You wouldn't believe it ofcourse so you went and asked him about it.

When you did tho he got all defensive and said "M-me??!! Like you?! H-hey!! Where did that information even come from!! I-I dont like you at all okay..." While obviously blushing from ear to ear.
