It looks... vintage I guess? Somewhat? ('97?)
The title of the manga is called Salad Days. It's a 18 volume collection of short stories and a few continuing mini-arcs mostly relating to love, relationships, perfect romances, and bad turn outs.
Every time I read them I feel so... mushy?
I'm a goddamn sucker for this stuff. Oyashiro-sama knows why I keep revisiting it within the past three years.
Anyway, anime-source hosts this manga for viewing here for free. It's good to read if you're bogged down with works.
Sweet stuff here (http://www.anime-source.com/banzai/modules.php?name=Manga&id=17)
