Thank you for the translation! I don't really like the MC or the FMC, as people have already said the desert stuff was a real asshole move and I feel like the FMC is just non-stop making him work overtime and is a bit of a bland character who has no real personality outside of work and the MC...
I still do not really like the poly route, and this chapter just kind of reinforced that. Itsumi goes on about how she of course would have rejected the third girl no matter what cause she loves Rin, which makes me question where the third girl is in it, since she just kind of feels stappled...
