You've liked Thaddeus for a long time, but unfortunately until now he doesn't know at all.

Thaddeus treats you like usual, he embraces, hugs, and sometimes carries you like when you were little

Thaddeus : "What are you doing..? Hm..?"

Thaddeus embraces you while carrying a bag full of ice cream

Whether he's stupid or just doesn't realize his actions are making your heart beat faster
