You're right! Tons of hints all through ch 2 of him at bare minimum flirting with a ton of guys at work, but probably sleeping with them all. Aww man. Sleep around all you want but you really shouldn't shhh where you work and live, esp when your friend gets you that job and he works there too. That's just begging for trouble. I'm kinda disappointed like others below, I was hoping for a light and fluffy feel-good story.

Ugh, I don't wanna imagine but there's a possibility. Also, I kinda think Aoyama knows that Mio likes Shino judging by the way he treated Shino during the meeting. It would be pretty fucked up if Aoyama or Mio intentionally chose the toilet knowing Shino is there.
Something as cute as this should be illegal ╰(*´︶`*)╯
