Hello, looking for romance manga suggestions where there are multiple couples where they try to help each other with their crush(es)

Examples: Tsurezure Children , Horimiya , ReLife

Others where the focus is on one main couple: Koi Inu., Nijiiro Days (MIZUNO Minami)

Preferably from the male perspective, but 50/50 is great too.

Judging from the raws, the later chapters of Hatsu Haru would fit. Unfortunately, the scanlations are only up to around Chapter 6 at the moment. It's still a nice read and might be worth checking out though (:

Renai Lab is the best fit. Then there's Bokura wa Minna Kawaisou that hints at other couples but focuses heavily on one, and Iris Zero that's still at an embrional phase under this aspect.
