They're popular because it's a very relatable concept. Many people have had a crush on someone and felt that sense of obsession at some point. It's also a bit of a fantasy for some, seeing someone be so dedicated to another person.
The popularity of 'guy obsessed with girl stories' lies in the fact that they explore the depths of human emotions. Obsession is a very strong emotion, and when it's centered around love, it becomes even more interesting. People like to read or watch these stories because they can see how the guy's obsession drives his actions, whether it's doing something really sweet for the girl or making a fool of himself. It also taps into the idea of the pursuit of love, which is something that most people can identify with.
These stories are popular for several reasons. Firstly, the idea of someone being so into another person is kind of exciting. It creates a lot of drama and tension. Also, it gives people hope. If a guy can be that obsessed with a girl and eventually win her over, it makes others believe that they can find love too. Moreover, it's a classic theme that has been around for a long time in literature and movies, so people are used to it and still enjoy it.
It could be that the art style and emotional depth of girl manga appeal to him. Also, some guy might be interested in understanding different perspectives and experiences through such manga.
Well, often in these stories, the guy starts as a bit of a stalker - not in a creepy way though. He'll find out her daily routine and 'accidentally' bump into her a lot. Then there's the plot where he saves the girl from some sort of trouble, which makes her see him in a new light. Also, there's the scenario where the guy writes her love letters or poems to express his obsession in a more romantic way.
Well, there could be a bunch of reasons. Maybe the guy has some unique traits that draw her in. Or perhaps they share common interests and hobbies that create a connection. Also, it might be his kindness and compassion that make her obsessed.
One such manga could be 'Love Beyond Size'. It shows a guy who is head over heels for a chubby girl, depicting their unique relationship.
Perhaps the obsessed guy has a change of heart. He realizes his actions are wrong and lets the girl go. But this ending often comes with a complex set of emotions and consequences for both characters as they try to make sense of what has happened.
Often, the theme of rescue is present. It could be the girl trying to rescue herself or her friends and family attempting to rescue her. Also, there can be a theme of psychological manipulation as the obsessed guy may use various tactics to control the girl.

Say, in 'Family Troubles and Her Comfort', the guy is having a hard time with his parents' divorce and the girl is there to listen, give advice, and just be a shoulder to cry on. Also, in a more sci - fi setting, a girl from an alien race might comfort a human guy who is feeling lost and alone in a strange new world in a story called 'Alien Comfort' or something similar.
Another theme is self - discovery. For the nerdy girl, she might discover a new side of herself through her relationship with the popular guy, like becoming more confident. And for the popular guy, he may learn about things he never cared about before, like the nerdy girl's interests in academic or geeky stuff. In many of these stories, there's also the theme of breaking social barriers. Since they come from different social strata in school or society, their relationship challenges the norms and expectations of those around them.
