"I can't bring a real high school girl" oof but I'm sure there'd be similar situations with like runaways or so
I get why he suspects the male coworker but no need if he already snitched directly/thought Sumire and Mirai would've said it could've been a female bc of the Watashi pronoun and other explanation
If this goes as Sumire planned then she's killing maybe ten birds with one stone.
Definitely not going to go that smoothly though.
Well even without her jumping into bed , just showing Kippei a pic of her outside a hotel building with an older stranger would be enough to fuel the fire even more/he prolly planned to divorce her for Sumire anyways
