They're such a wonderful couple! I know some others that you might like:
1. XXX Allergy by Hinohara Meguru
2. Eigyou Nika by Kanai Kei
This is one of my top favorite manga. The seme is so sweet, funny and supportive. The uke is precious and oblivious, at the beginning he gives this cute little speech about Toujou-san and says things like "It looks like it'll be really fun being with him. I want him to kiss me lots. Not just him kissing me, I want to be the one to do a lot of things to him, like biting him sweetly, I want to do so many things to him." Then he's sitting there like a sad panda because he's convinced it'll never happen, and Toujou sees him not knowing what he's thinking about, he assumes Ayumu is just tired/ill so he makes him rest his head on his lap. Waaah they're too much!
3. Liquor & Cigarette by Zaria Ranmaru
4. Chotto Matte yo Hanaya-san by Machiya Hatoko
You're welcome, I hope you enjoy them! I do like some dark manga, but eventually I just want to read something that will make me smile and shows a healthy relationship, you know? It's way too hard to find! If you want to see more cotton candy moments and you don't mind possible spoilers, I also have an album of approx. 200 images of G/PG pure fluffy cuteness. I titled it simply "Adorable". (⌒▽⌒) I can't promise that all of the images are from entirely light-hearted manga, but the selected pages are really doki doki parts.
I really love this yaoi, it's one of my absolute favorites! The uke is super adorable and the seme is really a good guy to him. It makes me feel fluffy inside. :-3
Does anyone have any recommendations of yaoi similar to this one?
