I hate to say that but I actually agree with you... the last couple lacked... deep feeling...
And I first shipped Hazuki x the girl big brother....
Then I shipped Hazuki x Tauma
But because in both case, there were deep feeling involved
Yeah, they should have shown us more developement of their feelings. It felt rushed and like the author totally didn't care about Hazuki ┗( T﹏T )┛
The other 'couples' were way better and cause Hazuki seemed like the main protagonist within our 5 boys it was an even bigger disappointement to how his romance story 'developed' and turned out （￣へ￣）
At some points in the beginning I did like girls bro/dorm head with Hazuki and also thought he might find out about Hazuki/Tsukiko being the same cause he DID notice they having the same wound on the same place. But no, nothing.... Why end a chapter with him being suspicious but then never going into it? Felt weird... Σ(っ°Д °;)っ
So he did have great potential. And truly I liked it a lot him opening up to Tsukiko but all the potential didn't get used... (〜￣△￣)〜
And Touma was like real big nice cause his feelings were for both Hazuki and Tsukiko, like him accepting him whole. We also saw way more how deep his feelings were.
And personally what Touma said quite in the beginning about Hazukis feelings to his love to Asumi kinda stayed true the whole story over in my opinion. I think it was sth like that Hazuki likes Asumi cause 'she is a nice girl and she interestes him bit that's not love, love is more complicating'
Pethaps Asumis character in itself was no good, that it was difficult to find any other points to make Hazukis 'feelings' 'deeper' because well I never saw any potential in any deeper developement in Hazuki x Asumi - perhaps I am blind but it felt shallow every single minute - they'd be good girlfirends as Tsukiko and Asumi bur nothing more in my eyes kinda.... (￣∇￣")
You just stated exactly how I feel...
I'm glad I wasn't the only one that was weirden by the fact that the dorm head noticed the wound but never did anything with it !!
I still enjoyed the manga, but like you sayed, I don't think I'm ever gonna re-read it , as sad as it is to say...
At first I though I was only dissapointed because my ship sinked, even if I already knew it since the begining, and it was only a matter of fangirlism...
But after thinking for a bit I came to the same conclusion as you, it's sad the author couldn't give Asumi more... I don't know... weight? in a spiritual meaning
I knew this was how it would end cause I spoiled myself with others comments before the translation was finished but I still feel disappointed (〜￣△￣)〜
Personally the Asami Hazuki pair is just too shallow (is that the word?) I was for Asami + bestfriend and Hazuki x Touma not because because its BL or GL but because Touma and bestfriend were way more serious and the couples would be cuter for me and Hazuki and Asami just don't give me any feeligs too not even the oh cute feeling. NOT gonna reread it though it had such a good start it ended as most shallow romance stuff out there with not a satisfying end╮(￣▽￣)╭
