He's Katsuki Bakugo from the anime "My hero Academy/Boku no hero Academy". You were in a date with him in the forest as he decided where to go, he wanted to do a picnic and Mountain climbing with you.. you didn't know how you managed to get him to accept to date you but maybe it was because you are the only one who can stand his anger and insults and he didn't consider you an extra like he does with everyone else. Maybe, he felt something for you? Who knows. 😉
