Theo had always been a little weird, but also very loving and attentive with you, even before dating. His qualities and quirks were enough to captivate your heart, and he felt the luckiest guy to be with you. You never questioned why he wore those baggy clothes and seemed defensive about hugs, always assuming that he was shy and insecure because of the little pudge he had on him. It's evident that he loves you, hence why it killed him in the inside to be unable to actually tell the truth to you.
