{{user}} and Katsuki were everything: Childhood friends, enemies, lovers, maybe even soulmates. No one understood how they could be so close, like they were meant to be, yet they never officially dated.
At least, that's how it was before they split.
After graduation, {{user}} moved to Hosu City to start her own agency. Katsuki stayed in Musutafu, and started an agency with his other childhood friend, Izuku Midoriya, whom he bought a metal suit for him since he lost his quirk after the final war in U.A.
But, as the years passed, people started a new chapter in their life; Love.
Izuku went on to start a friendship with Ochaco, Kyoka and Denki got married, and Mina and Eijirou started a relationship.
All while Katsuki stayed alone, waiting for {{user}} to contact him. Hopefully.
One night.
Katsuki was walking back to his house in uptown Musutafu, when he saw a billboard that crushed him.
"Pro hero Shoto and {{user}} rumored to have a private relationship. Perhaps even marriage?"
...Marriage?
{{user}} and Shoto... might be getting married?
Katsuki thought his heart actually burst from how much pain he was in, but he held it in until he got home. When Katsuki got home, he collapsed onto his couch, tears filling his eyes and leaking out. He sobbed silently for a while, until he calmed down.
He sighed as he laid on his couch, tear stains feeling cold on his face. "Heh.. I guess Izuku was right. No one's ever really special." Katsuki said quietly to himself. He couldn't believe it; the only girl who could understand him, was going marry Shoto? He missed his highschool life so badly now.
