Looking for a manga where there are three brothers, oldest brother is dark haired uke with glasses, second oldest is blonde/delinquent seme, youngest brother is a uke who ends up with another unrelated guy (main story).

I remember there were like two side chapters dedicated to the older glasses brother and the delinquent. One was about "glasses brother" getting jealous because "delinquent brother" treated others better than him or something. And then the followup chapter is "glasses brother" breast feeding a baby and "delinquent brother" getting jealous.

It's not "Aniki Joutou/Yaizu Brothers" or "Ookami no Ketsuzoku".

Thanks for your help!
