While Hanamoto just has the wildest thinking patterns, from being so dedicated to confessing for an entire chapter to being afraid he'll scare off Furuya again for wanting more. (which is what happened the first time he confessed)

By chapter 3, I get the sense Furuya is still not in "love" but wants to indulge in the relationship as a substitute for his love for Hashimoto's sister. This could be why people are confused and find it creepy that the author keeps pushing the relationship, but I think Furuya's actions are not of a person in love, so it makes sense.

Shinobu fall in love with Furuya way too sudden, they just met, talking to each other and had lunch together, and after that he said he liked Furuya, based on what? I don't see why he fall in love with him at all. It was like he feel that way just to fill the story, but i didn't feel the 'love' there. After that, just like any other straight guy in yaoi world, Furuya (who is just got rejected by Shinobu's older sister) started avoiding Shinobu after he confessed, by the way Shinobu said it he just want Furuya to know how he feels. But the thruth is Shinobu want him to accept his feeling and not rejecting him! Somehow i don't like how the way Shinobu act persistent and how they started dating like it was a game. And you know what? After a while Furuya told him that he loved Shinobu after they have sex! Really? Furuya love interest changed abruptly, how can you decide how you feel about someone else by having sex with them?
