I don't think Kichan was even expecting you to want that much. [you like boobs too much aomine, everyone assumes you're as straight as straight comes.] I think you should be honest with him. Tell him that you liked kissing him, and you're interested in maybe doing it again, but you've never thought about him like that, so you aren't sure if you return his feelings but are willing to give them serious consideration. Avoiding the subject isn't going to help you make up your mind any.
