@Raskaro the last few chapters? I remember them. She pretty much never showed (never did) that she likes him towards MC in any way. There were no signals at all. MC felt like shit in (almost) every chapter being self conscious and anxious (was showed and even put into words when saying "I am so lonely" while sitting next to her, lol). "The dude" is at no fault, author went bonkers thats why so many people complain. The progress wouldve been fine without every random "the dude" being closer to FMC than MC himself. Its a cliché try to progress the plot (the confession being overheard and every male being after Furi suddenly). I would argue the dude confessing is closer to her than MC for being allowed all alone with her together in a room, keeping a normal conversation.
She shows enough signals that she likes, or further downplaying it, is interested in him, but it is the dude that doesn't catch them.
The signals are not even subtle, they arent there. I dont know what you see but MC could never get any hints from what she is doing apart from considering himself a stranger (the overall consensus) and try to get with her. Thats how real life works too. There is nothing going on? Why risk and go for it. In the end he is "the bad guy" and characters and readers shit on him for no reason.
@Entryhazard true I was kind of going off there since you called something nonsense that I think wasnt. But Fredfriendly certainly made points that resonate with my opinion that we arent even sure anymore of what FMCs intentions are. I also said that yes she was shown to "be quite into him" at first but for quite some chapters now she made no effort to show him, at all. Just throwing that out there.
