Let's hope it won't become a test of strengthYou know he's completely romanticizing it, right? If you're looking for a more grounded version, here it is:
The chapter starts with Sanada and MC sitting at a restaurant talking about the threesome. Sanada is complaining about how hard that was in video game terms, before telling MC he can't handle her. MC tells Sanada he's less able to handle her than MC himself is. Then he says he wants to go home and draw.
Sanada goes on to point out, once again in game terms, that MC has a small penis and is a quickshot. He says he should have been dominating the threesome but then recalls the event, where the MC was crying (not out of overwhelming emotions or enjoyment—he was crying because he was watching Sasha get fucked right in front of him), and Sasha was focusing on MC, and wondered why he felt like he lost. After that he says that MC orgasmed 8 times in one session, yet he's still intact.
Sanada then thinks his instincts are telling him he has to get rid of MC before he grows stronger.
Sasha then talks to her dad about the video she sent (yes, she sent her dad a video of the threesome). She tells him that someone is adorable but then clarifies, "The short, crying one." This reveals that Sanada was part of the recording and was prominent enough that a third party didn't mistake him for a bystander, despite not being the one pinned down.
The rest of the chapter is the dad asking if MC is her boyfriend and her asking what he'd do if he was. Dad's quiet for a bit, then tells her he's coming to Japan in the next month because he has a match. He asks if she'll come, then tells her to bring the boy with her. Then she finally says she loves her dad.
According to the artist's other works that relate Sasha, her family has a lot of wrestlers/fighters
