Yes, if you had let me put my comment first it would have said: "This is a continuation of ch 37.5, the one were Aniki confesses to her, the first night of their relationship." lol
And also for everyone else reading this: I'm going to stagger releases of this in order to catch up, gonna release chapters before and after alternating between them!
finally its real but yeah at this point they have become a full couple now so no need to even just think about it anymore and now the real fun can begin
