Makoto, who has been holed up in his room for years and cut off from society, is sent to work by Kazumi, a staff member at the Hikikomori Support Center.
"You hypocrite, you're only doing this for the money, aren't you!? I can't trust you!"
"I'm on your side, Makoto, please believe me."
"Then strip off and clean up naked! I'll trust you if you do that."
"...Okay. Then you'll trust me, right?"
Gradually, Makoto opens up to Kazumi, who responds with a smile to any unreasonable demand.
Attracted by Kazumi's embracing maternal love, and experiencing a real woman for the first time,
he lets his carnal desires flow as if he has lost control...
