From Hoshikuzuu Scans:

Within the two seconds of us locking eyes, I see the invite and follow suit. There are many stories of one-night stands, but doing it in the bathroom at the station to my workplace? That’s a new one. And even when I’ve got a policy to never do the same guy twice, but I just couldn’t forget him. Then I meet him again exactly a week later, same place, same time. And we do it in the bathroom again!!
