Yukidoke no Koi
Main story ended well (chps 1-5). Plus 2 angsty oneshots - all unrequited love - the author really knows how to write angsty, bittersweet, heartaching unrequited loves. Main story spin-off about the friend who went with him in college (yes, also unrequited and realistic love). Happy ending though. http://www.mangago.me/read-manga/bokura_ga_koi_wo_ushinau_riyuu/

Bokura no Tsuzuki
This was really sweet like candy to my soul Summary Highschoolers Yousuke and Shuu have become somewhat estranged due to an accident early in their childhood. However, their relationship is restored when Shuu moves to the shopping district Yousuke resides in, to stay at his grandmother's place. Yousuke, although akward at first, starts feeling stirred by the expressions and mannerisms that the usually aloof Shuu only shows to him!
