I have to say, I'm even more excited for the next update. The conversation with the youngest sister, which is only partially rightly chastised as a source of problems. What's going on between her and John is definitely something that gnaws at her and is impossible for her to solve on her own because of her not-so-easy personality (which, however, might also be due to the problem, so it throws her off balance emotionally and that's why she is the way she is). Another problem is probably the general difference in personalities: John communicates more logically and objectively, while his youngest sister communicates more emotionally. From personal experience I can say that such combinations are a powder keg and it will most likely take some updates until the two are at peace with each other and the problems of the past are worked out.
Regarding Yukiko and her mother: I think that will also take some time to work through. I am convinced that sooner or later John will tell the family members who don't know about it that Yukiko is his daughter. And I would say that Yukiko deserves it, because she had to hide it from most of her family all her life.
What I noticed the other day is that John's first memory with Lena is one in which she insults him a little, which reminds me of the Simpsons episode in which Marge loses her memory and she remembers Homer by the mention of beer.
