Any SFW gay manga recommendations

I've been on a rush of reading manga recently and have been reading a few gay manga. A few were really good (I especially recommend stuff by Okura like I Think Our Son is Gay and That Blue Sky Feeling), but I've struggled to find a manga that's about being in a relationship, rather than building up to one, and the manga ends as things start. I've read a few more as well and they all kind of follow a similar pattern.

So, any recommendation for a good gay manga, not about sex, about a relationship rather than building up to one.

Much appreciated.
