For a first release, this is quite simple, yet real good. The renders (especially best girl Cassidy and daughter) are great and the dialogue seems coherent/fine (maybe some typos or such here and there, as always with such things). The story sorrounding the wife while maybe not the focal point of this, is rather interesting, I personally don't know If I'd stick around, yet the MC seems to love her, in some way, while for her it almost looks unconditional.
My biggest problem is that maybe the plot is progressing too fast, Kayle already going to live with the MC. Now sure, he's helping out a person in some real real need, yet somehow even thought the 1st chapter/update spans several days, no one thought "Huh, lets get a test and see if she's for real".
Anyway, all is good, I hope this continues and it would be great if this was a harem game. Would absolutely love to see Cassidy and the daughter fight over the MC
