Kaoru needs to take her ass to therapy ASAP
Correction *Everyone in this manga needs to take their ass to therapy, after rereading the series, everyone seems to be going through some sort of shit.
*Reiichi: Doesn't love his wife, still in love with his ex, chained up to a fake marriage born out of pure guilt, has been carrying the weight of a promise for years and can't let go.
*Risako: Cannot accept or understand her own feelings and ends up destroying them, even went as far as to get between a marriage, lack of empathy.
*Kaoru: Has been showing signs of depression for a while now, is in a fake and toxic marriage.
*Uta: Doesn't really have "issues" infact she's actually distancing herself and recovering from the hurt of unrequited love, which is a good thing, but she's sure as hell gonna catch some if she doesn't stay away from Kaoru, but what are the chances that'll actually happen?
