I need a MikoRin fic where Mikoshiba and Rin are already dating but Momo doesn’t know and doesn’t figure it out until Mikoshiba comes by Samezuka for a visit and just kisses Rin.
Momo does not approve.
At first everyone’s confused why he doesn’t approve since he’s always liked Rin and is pretty attached. Then they assume it’s cause he’s crushing on Rin too.
But nope. It’s cause Rin is his mama and his brother does not deserve Mamatsuoka.
