Kiss Blue
This is one of my favorites that I "walk away" from for a few (6+) months then have to come back to read because I missed it --- these guys are like my friends :) Also - I've seen lots of comments about the art style but I kinda like it myself --- I dismiss the parts I don't like as "whimsical" (i.e. the hand sizes in many of the frames) and just enjoy the parts I do like (i.e. the eys).
Brothers (YAMAMOTO Kotetsuko)
Spoiler Alert: Anyone else bothered by the fact that on this page http://www.mangago.me/read-manga/brothers_yamamoto_kotetsuko/tr/90235/page/18/ he says he's worried about his mom's happiness since his dad died but later in the story you find out they were just divorced, and he goes to his dad's place?
