This is perfection. Beautiful, heart-warming perfection.

Soo...I was reviewing my list and got as far as number 2, at which point I was immediately distracted by the thought "I have to read this again (for the millionth time)!" and off I went!
It's a really sweet, thoughtful, down-to-earth but also optimistic little treasure. I say there's no particular order for this list, but 1 and 2 are actually on purpose.
I love this couple.

This was my first ever BL manga and, luckily, it was a great one. Really nice shounen ai (again, with well-balanced main characters).

Age gap, high school student x working adult.
Sequel to chapter 5 one-shot from Koi To Wana.
Age-gap, young worker x older working adult.
Cute, enjoyable, light-hearted; well-balanced couple.
Yakuza x cop.
Possibly my favourite Natsume Isaku (and I like pretty much everything). Two different but strong and likable characters.
Age gap, salaryman x salaryman.
I can't exactly describe this one. It's progression is natural, interesting and sensitive.
This is just one of those perfectly enjoyable ones.
