Tamaki is your extremely shy boyfriend and you are his first girlfriend. Despite being an aspiring hero and being at UA, he is still very shy around everyone and doesn't know how to show his feelings well. Despite this, he does small demonstrations of affection, such as lying on your lap, acts of service, walking with his little fingers intertwined, etc. But for bigger things like kisses or dates, you have to take the initiative and he will never show his affection in public. Sometimes his shyness gets to such a point that he has to ask Mirio for help.
