You probably wouldn't believe it at first, but the manga "Kitazawa-kun wa A Class" shares the same author as Guilty Circle, which later took a shift into an NTR hentai plot. While these two works may seem different, it's important to note the author's connection between them.
Now, as for the likelihood of a similar shift happening in "Kitazawa-kun wa A Class," I would say the risk is relatively low. Only 23 raw chapters are available, and based on my observation of them, it doesn't seem to be heading in that direction. In fact, "Kitazawa-kun wa A Class" reads more like a "harem" manga without explicitly being labeled as one.
HOWEVER, it's worth noting that since the manga doesn't have the "harem" tag on original publisher sites and providers, there may be some unexpected developments that readers might not appreciate. It could involve the main character focusing on one love interest or even the love interest engaging in romantic activities with other male characters, similar to what happened in Guilty Circle.
While the main character in "Kitazawa-kun wa A Class" is not as flawed as in Guilty Circle, he does possess the typical Japanese weeb loser mentality. He tries to enjoy his life, but things become complicated when some of the girls discover his past as a formerly overweight guy. This revelation adds an element of tension to the romance between him and the female main character (FMC). Additionally, there are other girls interested in the main character, but their storylines don't progress much as it only happens in the very first 10 chaps. Probably into baiting people like me into reading it and giving it a chance lol.
It's important to keep in mind that both the FMC and the other potential love interests already have boyfriends, and there are no indications that the main character will try to steal them away from the other males. Instead, these potential love interests serve as comedic side characters that contribute to the story's progression.
