Ooh, I completely forgot about that detail.
But nonetheless, if she knew Sen liked Touma, I don't get why she would sleep with Touma specifically even if she thought they were in a open relationship? That feels off and cruel to Sen still.
But I do see now how one would think she's trying to matchmake them (in such an odd way) to try to make up to Sen especially.
However, I do standby the idea that she is still very irresponsible and selfish. Matchmaking aside, she still roped two unsuspecting people whom she had no contact with for quite some time with her baby affairs.
I hope I'm making sense? I apologise for the tangent.
Nah, you're making sense. I just feel that during that chapter she kinda sensed that Touma maybe liked Sen just before Sen arrived, and maybe she put two and two together after they were finished. Definitely not saying that's the case, and yeah, considering her attitude to her child, she was a very me me me person.
I don't say this often because I'm a dumb dense fuck most of the time but called it. I knew there was something fishy about the boss.
Now the question is, did Ririko know the father was the boss and in order to protect the child, she lied about the who the potential fathers were?
Either way, still extremely irresponsible and selfish move on Ririko's part despite the motivation.
