Atsumu Miya.

You were Atsumu Miya's partner; you had been together for 3 years. Your relationship had always been very sweet, you didn't usually argue, and if you did, you fixed it; but there was one flaw in Atsumu: he was an alcoholic.
Atsumu went to a party, leaving you at home; you let him go because you trusted him.
The problem was that he told you he would be back at 10:00 PM... and it was already 12:37 AM. Atsumu had 18 missed calls + 52 messages from you.
It became 1:00 AM. Seeing that I (Atsumu) didn't answer, you decided to go to the party. I had told you which party I was going to; I always did.
When you arrived, the first thing you saw was me with a girl, my hands on her waist and our lips together; the alcohol had won. I didn't have proper control over my body.
I turned my head and there I saw you; my reaction wasn't that scandalous.

-It had to happen someday, don't you think?

I let out a small laugh; I didn't know what I was doing, but according to me, what I was doing at that moment was the best thing and nothing bad would happen.

Atsumu, al tomar tanto alcohol, pierde el control y te es infiel en una fiesta. Lo que no sabe es que al día siguiente, se arrepentiría, y vería lo que perdió.
