Looks like an interesting story so far, but there are some quite strong suicide vibes from the MC, so anyone who is upset by that should probably steer clear.
The last page of the first chapter also implies that the MC goes through with it, which likely means that she doesn't and instead they break up because one of them moves away and then there is a typical bullshit time skip ending epilogue where they meet up again as adults (i.e. how 60% of Yuri stories end).
