I need help

Looking for a yaoi where the mc offers a 'rent a brother' service and it's intended for mostly girls who wanna go on dates but this new client is this younger intimidating looking guy who wants to actually rent a big brother. The mc thinks it's meant in a dating way but the client just wants to feel like a little brother for once and they end up in some misunderstandings. Their relationship turns romantic/sexual later.

I forgot the title and can't find it anywhere. Pls help ;-;
