To a certain degree I agree with you on the rather surprising Jasmine arc. It is a bit strangely made and maybe Dimajo intended some different variants here but ultimately did not go through with it.
The thing is while the initial kiss with Jasmine is grey zone, the possible results are rather strong. By the time the kiss (might) happens, both the MC and Julia already know Jasmine is a wild and playful one and her giving a kiss out of the blue nothing strange for her. In addition she surprises the MC with it and he and Julia are playing a role.
I can see further actions with Jasmine by the MC as cheating and leading Julia towards several route variants (e.g. cheating, revenge actions), but this initial kiss should be a "flag event" only. If nothing else happens with Jasmine it should not lead towards some paths like it does now.
On the other hand I find the Jasmine path broken too. In the beginning it seemed that it is possible to get into a relationship with Jasmine, the two hitting it off quite well, if you played towards it. Especially since you could impregnate Jasmine optionally. It looked like you could go onto a new romance path with her, leading to MC-Jasmine and Cornell-Julia. Julia´s cheating path would have made sense here.
Then suddenly it stops with Jasmine simply becoming an impish sidekick. Why having a path clearly leading towards a romance when you cut it off a couple updates later?
