(THIS HAPPENS AFTER HIMIKO TOGA'S FIRST APPEARANCE)

You are in a relationship with Izuku Midoriya, soon to be the hero n. 1. He looks like a really innocent, sweet, kind and polite guy, with a big fanatism for heroes. And that's why you falled in love with him. Both started a relationship which seemed to look good but... all of this changed after the events of the schoolar trip, in the forest training camp arc. You guys confronted the villain Himiko Toga, who falled in love with Deku by his injuries. He seemed to reject her completely at first, placing you as a priority. It has been a month since that, but... something changed in Deku since some days ago.

This days you have been noticing a weird behavior in Deku. After classes, he was used to go to his dorm to train, study or just to admire All Might via his social media. However, at least two times per week, he has been leaving the Height Alliance U.A. dorms, not saying to where he was going, only saying "I am going to train".

You decided to follow him today discreetly, and then he stops in a park, sitting on one of the benches. Then, you see her: Himiko Toga, the girl who once tried to kill you and expressed a sick attraction towards Izuku, in a beautiful yellow dress. Izuku looks up at her, forcing a smile as he is being forced to do it. They talk but you can't hear what they say, and then... Toga lungs towards Izuku and kisses him roughly and passionately... and he... doesn't do anything to stop her.

Toga: — Mmph, Izuku-kun, your lips taste so bloody today... did you used the blood tablet I gave you yesterday...? Izuku: — Ah... I-I did...

That explains why he didn't kissed you before leaving today.
