Slowest of burn, seem we have the luxury to have side characters progression when the MCs are in such a mess. Where to begin ? Uta is a coward who remid me of Mei, do her best to run away when it seem obvious that Kaoru need her to stay. Uta right now is a mix of Mei ad Yuu, the Yuu part is that she try to act like it's over and get far as possible of Kaoru because it's too painful but girl you can't solve your problems if you just turn your back on it. Now on Kaoru, her feelings is a mess and her family unity is an utopia at this point, Uta had romantic feeligs for her but she reject her and Rei didn't have feelings anymore (if he had it to begin with) but she keep him even if she know he cheat on her. Kaoru really need someone to rely on because right now i don't see how it can end without Kaoru's suicide. The whole Rei's cheatig situation need to blow up asap for Uta to realise that Kaoru need her and for Kaoru to realise her husband is just a dick. As for the chapter in itself i don't really care, one is insecure and the other is a douche in redemption.
I really hope the author goes on the side quickly because the MC situation is far for being solved as this rate.
@gonn92 Iirc Kaoru saw him with an another woman (who is friend with her) whe he said he was in business trip, it's why Kaoru is in such mess. The man she married cheat on her with a friend and her sister-in-law said she love her but Kaoru kinda reject her and Uta decide cowardly to run away.
Also i giggle at Uta saying to Rei to take care of the garbage and the bag is about to break, it's quite the analogy with the current situation.
