I'm looking for a novel where the mc must care for the love interest because of a system (or unforeseen circumstance) and the mc thinks that they are just really good friends or maybe even thinks that the love interest doesn't like them at all. But the love interest falls in love because they think the mc is caring for them because they love them. Everything is fine yaoi, yuri but no harem, loli, rape. I just want a heartwarming love story filled with misunderstandings. A novel like "The demon king always thinks I'm secretly in love with him" and "Don't you like me".
Noble Wife Wants No Romance is suuper fun. The ML suddenly gained the ability to hear the FMC transmigrator's inner voice, where she bash his head many times internally while placate him with sweet nothings.
The Target Always thinks That I Like Him Transmigrated into a School Idol and Forced to Do Business It's not Easy Being Your Love Rival's Brother
These are ones that some what fufill your request but not really "My Wife is my Life" might also be another one, except this time the ML has to pamper he MC because of a system. It's really funny though and I definitely recommend! "Marrying the Soft-hearted Villain' might also fill your request because the MC has to care for the ML although I haven't read far enough yet so I don't know if the ML misunderstands her good deeds for love or something and falls in love, but it seems to be going in that Trajectory so its worth a try
