It's a decent start. There are some issues, though.
- Words are randomly capitalized, often after a comma, sometimes just like that. And on the other hand, some lines start with lowercase. There are also lines ending without a period.
- There is a weird inconsistency with commas. Some lines have plenty, while others have none. It feels like two different people are writing this.
- It would be nice if we, the readers, could tell if the MC is speaking or thinking. If there is a distinction, it's too subtle for me.
- The MC's name is written in all caps at the top of the textbox, which looks especially weird because he's the only one that happens with.
- There are a couple of definitions missing from the patch, namely "siblings" and "parents".
- MC calls his mom "Mom" most of the time, but there are a couple of scenes where he calls her by name, which feels out of place.
Finally, while I don't agree with everything they said, Trasher2018's comment above rings mostly true. The player's choices feel largely ignored, the dad is brought up quite a lot more than I'd have expected considering how long ago he died, and there is a noticeable lack of buildup. Especially the mom's behavior, though drunk, seems unbelievable.
Actually, I should add something... After choosing not to have dinner with Kate, the MC goes to his room and play some games until he gets hungry. And then we're treated to a slideshow of him finding Kate drinking wine on the couch, sitting down with her, and talking to her, completely without text. It's so obvious this was just put in as an afterthought.
And my last point (this time for real): There is a distinct lack of transitions or narration, which makes reading this a little disorienting at times. For example, one moment we're in the kitchen and Julia is about to go take a shower, and one hit of the spacebar later, we're sitting in front of a painting, and I go "Hang on, what?"
