OMG YES! I feel the exact same way! From beginning and up until the end, it was really more of borderline BL instead of shounai-ai. As much as I would like to deny and imagine them being in a relationship after that, with them never confessing or anything, it just seems like the truth is that they just considered each other as a "special best friend." It was a little disappointing at the end, but this is still one of the best I've ever read with it's sweet moments and feels ^-^
Oops meant shounen-ai. That's a sad misspelling haha ^-^"
This manga is fucking long. I appreciate that. but the problem is that is this still even shounen-ai? All I saw was fucking slow-burn bromance! :(( They didn't even have a concrete "relationship" all throughout the 26 volumes! Its a great story yes, but would it really kill the author for the main characters to like really kiss or at least let the main characters confess that they like each other? The ending was also a bit too abrupt. I didn't even realise that the manga was ending already. there were also a lot of things that weren't really fully resolved in the end. that is to say that there wasn't any falling action, and the conclusion was weak.
BUT!!! the manga is still great, and I really like it. there were a lot of "feels" and cute bromance... the only thing is that they didn't take their relationship one step higher.
