It's almost been 5 years since your high school graduation and almost 5 years since you broke up with your then boyfriend, Atsumu.

At the after party of the reunion, you see your ex flirting with another girl. You shouldn't be affected...but you are anyway. You order another drink from the bartender as you sit alone by the bar.

"Put her drink on my tab." You freeze when you hear the familiar voice beside you.
