Basically I'm looking for slice of life/romance manga similar to Horimiya and Bonnouji that have the following characteristics:
-One clear couple from the start with a minimum of challengers or love triangles, or even better none at all.
-A general lack of drama and angst
-Focus on the couple simply living their lives

Bonnouji is the absolute ideal when it comes to this, Horimiya has some small amount of drama which is fine, it's hard to make a series with no conflict whatsoever.

You can find what I'm currently reading in my profile, thanks a lot in advance.

maybe:
Love Roma
Mahoraba
B. Shock!
14-sai no Koi
Yome ga Kore na Monde.

if you liked Horimiya, try Nijiiro Days (MIZUNO Minami)

Love Roma

in need of romance?
uncommon, sad, sweet

I read Love Roma yesterday and it was fantastic, thanks for the recommendation. I also recently read 14-sai no Koi which is almost exactly the feel I'm going for,although the focus on them hiding the relationship is sorta annoying.

I'll look into the others, thanks a lot for the recommendations.

Maybe Densha Otoko - Net Hatsu, Kakueki Teisha no Love Story

Maybe Densha Otoko - Net Hatsu, Kakueki Teisha no Love Story

No. (granted I only saw the live action... if that was any indication, no. lol)
