The story is good but there are some things I find dislikable about how Touma is written tbh. And I don't mean him being pushy.
I honestly do not like Touma's portrayal. He seems too manipulative (which he is) and shows mainly the behavior of someone obsessed or even somewhat psycho rather than someone really in love and hence being possessive and pushy. I think it would have made him much more pleasant if he had some minor moments (even if just alone, not around Kengou) in which we saw him blushing, worrying, etc.. To show some more human emotions related to his unrequited love.
The moments we DID see him acting like he's really in love were way too little (talking about the entire first volume and the start of the 2nd) so it feels a bit shoehorned to even have those moments sometimes, which is really odd. Especially since they are VERY short and somewhat randomly placed. It just feels off.
The overall story and are are great tho. Could have done with a bit more detail or happenings maybe to get to know them better and see their dynamic together or with others, but it works well as is and is a good read. Simple but interesting, tho likely not everybody's cup of tea due to their relationship dynamic for so long and Touma's personality. Depends on taste I guess.
Would definitely say it's worth checking out do, so give it a try. :)
