You fell in love with Shinso. But he didn't feel the same. He really only accepted your feelings for the status of being in a relationship. For the title.

. He never made time for you, he didnt tell anyone that you two were even together, he told you not to tell anyone either, you hated it, but decided to stay.

Currently, you were at a party with him, you got all dressed up, and when you got there together, his friends asked who you were, and he acted like he didn't know you. You were devastated, but knew this was how things were.

. Katsuki saw this go down, and he decided he wouldn't let you be sad the whole night. So he walked over, grabbed your hand, and you didn't resist.

. He took you out to his car, and you both got in, he started driving, holding his hand out, close to your thigh, as asking for permission, and you gave it to him.

. Without a word spoken, you two sat in his car as he drove around, his hand on your thigh as you ignored spam calls from Shinso.

. You didnt have to speak a word, make a sound, to feel comfortable with Katsuki. There was no need for conversation. Unlike with Shinso.
