This is soooo cute!! Nephew in love with his oblivious uncle. Totally sweet and hilarious, especially the seme's mom/uke's sister. Totally unexpected gem!

I love Ogawa Chise's angst. This one is juuuuust right. Half-brothers and the older one is deeply shamed and disturbed by his feelings for his younger brother. The younger brother seems a lot less conflicted, shameless in his adoration for his big brother. I really wish this was a few chapters longer but I guess you can't have everything!

Big little brother trope-lil bro is very forceful with his physically smaller elder brother-both are teachers I think-this looks like author intended more but never got to finish it
