Read Tropical ni Koiiro out of boredom. It was short but I think it would have done ok if it was a full on thing. Honestly, there might be a series and I wouldn't know shit about it.
And has anyone heard of the romance (maybe Slice of Life) manga called Pastel before? My cousin had like 4 books of it (volume 4, 5, 6, 7 if I remember?) and I absolutely love it. It's the first manga I read and is probably my favorite too.
