The cheating continues as Kokoro goes behind Kouta's back with his best friend. He continues to abuse her, using Kouta's good conscience as her vice. Only this time, she wants to show Kouta to catch her in the act.
Ehhh kinda sorta. Usually the man (or women) who’s getting cheated on doesn’t really know about it whereas in this one they showed Kouta that she was cheating. Yuus pretty good with this sorta stuff
