The bad part about reading a crap ton of school life rom-com is that you start predicting tropes that might come true. The two tropes that I absolutely despise are the "MC-kun is not looking at me therefore I will make him jealous by having fun with another boy" and the "FMC-chan is hanging out with another boy. I must stalk them to see there is nothing weird going on". There is also the addition of another girl thus making it a triangle, which is honestly garbage. This is why when rom-coms don't do that, I hold them in extremely high regards. For example, Horimiya.
It's been only three chapters but let's see where this goes.
