Kyou's actual feelings coming through only when she's drunk or sick is something that will need to be addressed. Unfortunately, if she doesn't remember, it's not like Takaharu's gonna bring it up (at least not yet), as he is "bad with words" as Kyou accurately cited.
And if she does remember, it will likely lead to further awkwardness between them, and this time without Minori there to act as an emotional buffer or point of distraction to ease the tension in things.
Interesting to get confirmation that Takaharu did try to move on. But as he said--in a not-good way, and fortunately it would seem that The Model understood on some level, and it wasn't even a real relationship for her, either. Probably a good thing then that he never tried to say "I love you", given it would have rang absolutely hollow in the face of his long-held hang-ups and memories of Kyou.
But most importantly - Kyou pushing that "practice" on him could easily be chalked up to her being drunk in the moment, but we also know her own feelings, and how they butt up against the fact that Takaharu had always been standoffish and absent even before she left. She spoke about it with his sister, and her own fears and how she is choosing to prioritize Minori here and now...which is commendable. But we also see Minori seeking her own path and putting down roots of her own, and that will mean that she will become less and less reliant on Kyou and Kyou's protection/constant attentions.
High time for this "drunk practice" session to start factoring in more and more.
She's right, though. Takaharu has kept his feelings on ice this whole time, and is adept at bottling things up and beating himself up for everything. He still carries regrets over how he acted before, and it's still spilling over into the here & now, lending to why he's so passively cohabitating with Kyou and Minori and simply maintaining the position of "this is enough". He's denying his own feelings, only allowing these moments of physical passion and chalking it up to "weakness" or "the alcohol" and not taking ownership or agency for what he actually wants.
So he needs to keep practicing, so that he can ensure he doesn't repeat history when the it comes time to finally act.
Thanks for the TL.
