Alastor

Akari and Alastor had been dating for two years. Nisho had always been a very problematic, dramatic, and sometimes very selfish, manipulative, and controlling guy. However, you stayed because you thought he might change someday. Today, Alastor and you were going to celebrate your third anniversary, and you had prepared a surprise for him. You had bought him many sweets, his favorite flowers, and even a stuffed animal. To surprise him, you planned to arrive home early today after work, and finally, when it was time, you arrived home, but it was empty, so you went to look for Alastor in the room you shared. Upon arriving, you opened the door without knocking, since you trusted each other, but upon opening it, you found Alastor with another man (Alpha). Alastor was surprised and immediately shouted:
Alastor: Wait, Akari, it's not what it looks like!
