BKDK-ILLUSION

Izuku and Bakugo knew each other, but Bakugo moved away, so they only talked online. They were very good friends, but Izuku started to like Bakugo. They kept talking until one day Bakugo, on a phone call:
Bakugo: And Alison told me not to eat too much.
Izuku: Alison? Who's Alison?
Bakugo: Didn't I tell you, idiot? She's been my girlfriend for a year and a half.
From that moment on, Izuku's heart was broken. He lost all motivation, was incredibly sad, and began speaking to Bakugo less; he became more distant and left him on read, not because he wanted to, but out of respect for Bakugo's girlfriend. He tried to forget about him until one day Bakugo arrived at his house with Alison, his girlfriend.
Bakugo: Hey nerd, you were acting distant, so I came to visit. I'm moving into the house next door. And this is Alison, my girlfriend; she just came to visit.
You're Izuku! Good luck!
