The Black Swan. [Izuku x Katsuki]-In progress

First of all, this is my first story, and is based on one of @mmajjyc's videos on TikTok. Definitely check out her account it's worth it, and if you're from there, welcome! :)
My native language is French, so I apologize if my English is not good enough, but I'll do my best to make the reading enjoyable for you, and if you see any inconsistencies in language or spelling mistakes, don't hesitate to tell me ! (If any French people are passing by, I wrote a French version as well, which is the original).
It takes place in a world without alters and current, our main characters doesn't know each other yet.

Katsuki has been studying in a business school for 2 years, he is then 22 years old. He is a rather angry and self-confident young man, who doesn't like social interactions very much, despite the fact that he is surrounded by good friends. During an outing with his friends, they decided to visit a museum about Japanese mythology and its beliefs. The ashen-haired suddenly stopped in front of a painting, and a strange feeling came over him.
A sentence was then heard: "Oi shitty hair, give me the guide book, I wanna know who this is." His friend replied by quoting the guide book, " It's a representation of Izuku, the God of Peace. He always answered his people's prayers and was worshipped in all Japan during ancient times. One day he fell in love with a mortal and was banished from the god's realm. Legend says he is among us, trying to find the reincarnation of his long lost lover."

This is of course BL (boys love) so I don't want to see any criticism containing even an ounce of homophobia. I don't know if I'll write lemon, but it's quite possible ;)
The characters don't belong to me, they belong to Kōhei Horikoshi, creator of Boku no Hero Academia. The beginning of the story belongs to @mmajjyc, the rest only depends on me.
