Full disclosure: I haven't finished my first playthrough yet, but I'm a little disappointed so far :(
I came to this game after finding (and playing/replaying Our Life +DLCs (neeeeeeeed that part 4 in my life!!!)) so I was expecting it to be similar to that in the sense of being able to make choices that influence the MC's personality/the conversations. However, so far, it looks like MC is basically set in stone. To be fair, there's nothing really in the description that should've made me think the mechanics of the game would be anything like Our Life, but given the fact that two of the minor characters in Our Life are actually romanceable here, I must've assumed some of the things that make Our Life so great would be present here.
Getting to choose what kind of "jerk" MC is through dialogue choices would've been great because right now, I just find MC annoying, which has been making it hard for me to get invested. Like I said, probably my fault, but still somewhat disappointing!
I'll keep pushing through to play through the game, but it's definitely not going to be the shameless one-sitting playthrough that I did with Our Life lol.
