Senku X Reader (He's Mine)

I met this guy who's really love and devoted to SCIENCE! He is Ishigami Senku, but I have this feeling that I want to reach with him, this feeling of love. But how? How could my feelings reach for him? He's too serious with science. How can I tell him that I love him so much? I don't have much courage to do it but I'll try my best. Does this really work?
