I think it’s because he said the exact same thing to her “your so cute I don’t want to see other guys surrounding you” ig?
Because he liked her at the time and probably for the same reasons that's not a crime and not a reason to be jealous
if you had a boyfriend and he complimented you with the exact same words he used with his ex wouldn’t you feel idk uncomfortable ig.
I do understand your point tho
No I wouldn't because that just probably means he has a type or he's uncreative
MC is a complete beginner in love, like of course SHES gonna have naive and dumb thoughts like that XD that’s just how the process of having a relationship and beginning to understand of feeling jealousy feels like
See here's the thing so am I idk why people think extreme jealousy is normal its not
Everybody experiences things differently lol. For example, there are some people who are super clingy and possessive and some who are more laid back and some people like me who are aro lol. Everybody has a different way of going about a situation and the MC of the series is a super super beginner to romance in general. (Refer back to chapter 1) so something that seems like common sense to you could be different for someone else.
"Oh he did the same thing with his ex" .... yeah .... cause they were dating !?!?! I mean did you expect him to have never complimented or been affectionate or jealous with his ex they were still dating he still used to like her what exactly is the problem here
