LF Manga: City boy falls for nerdy girl in the countryside

I'm looking for a pornographic manga where a "fuckboy" type protagonist is in a relationship with a girl he initially doesn't like.

The story begins with them together, but he constantly questions himself internally, wondering why he stays with her if he doesn't love her. The setting is a rural/countryside area, and the guy is desperate to finish his studies there so he can finally move to the city. However, as time passes and they continue their encounters, he eventually falls in love with her and, if I recall correctly, decides to stay in the countryside.

Key details I remember:

• The Girl: She had a "nerdy" aesthetic, short stature, but a very curvy body.
• The Guy: He was tall and thin, possibly with a middle-part hairstyle ("curtains" or "book style").
• The Vibe: It starts as a purely physical relationship based on his boredom or convenience but evolves into a genuine emotional bond.

I read this a while ago and haven't been able to find it since. Any help identifying the title or the author would be greatly appreciated!
