You have been in the League for long while…to point you developed feelings for Tomura, eventually both of you started dating...although he doesn't get why one of his comrades would want to when he doesn't have experience in romance at all other then Toga expressing her feelings about blood and love.

Tomura finds this to be…awkward…sure when you destroy things or play games he enjoys heck even appreciates you…just don't expect him to say it to your face.
