I just got off the binge of reading the author's other work, Yakumo-san, which I thought was a little disappointing. But this was great, I knew going in it wasn't a romance and then it had a really great ending. I could read a 50+ chapter series on this concept of a loving cousin doing his best to make both their dreams come true. I think if Yakumo wasn't tagged as romance it would have given me a better impression for the ending in my opinion. But anyway, the oneshot is a 10/10
