Mata Ashita
Heart-warming, especially the one with the cute salaryman and the hunky mover/worker, but also the one with the office coworkers. This mangaka is so good <3
Nekasenaide
Again 3 couples, ranging from cute first love to bitter reunion, everything tugs at heartstrings.
Chotto Matte yo Hanaya-san
This is the first work I read from this mangaka, her most recent I believe, which actually got me hooked, and you can see the art progression through the years - not only she got better at anatomy (which was pretty darn good to begin with), but she changed her style (the lining/tracing is different now, the pencil seems more obvious and fuck if I know how to describe that) and the way she draws faces is no longer the same (it used to be elongated, sharp jaws and angled eyes for seme, big eyes for uke, now faces are more round and the seme/uke stark difference that is yaoi trademark for pretty much all the mangaka is no longer present). I absolutely love this story, it's fluffier than her other stuff and the age difference is handled well, all yaoi things considered (it's 10 years, though no one is under 18, with older guy putting up boundaries until later on).
Itsuka koi ni naru made
It's licensed by Renta, but only one extra chapter is out, will buy. It has a sequel that I also love. Edit: So happy I could read the whole thing - and, god, do I love the art, the strokes are so smooth. Very sweet, with coming out dilemmas (and a coming out scene right at the end that goes unfinished - can't remember how things stand in the sequel, will reread it now). It wasn't until the last scene with Tomoe that I recalled what the sequel is about, it's been such a long time. Edit: Part of my manga haul from Fnac Les Halles, what a great day this was.
Kazoku Ni Narouyo
This is so unbelievably cute and with minor drama regarding gay relationships (I have no idea how calling your bf 'partner' openly when picking up your foster daughter from kindergarten would fly in the real world, but I'm down with it). The prequel has more polished art, since it was drawn later on in the mangaka's career, but this is beautiful and wholesome.
Sick
This is cute, the seme is a bully but not an extreme one.
Konbini-kun
This is so heartwarming, there are 2 stories and they both hit the spot. The second one, about the salarymen in a relationship that only get to spend an hour a day during breakfast, was so, so sweet and angsty and I love that scenario. Spanish
