These are just some (I have many more recommendations) manga that are either much more mature than the norms and touch on tough subjects, or are simply reflections of love and life that leaves you fulfilled after reading. Hope you give them a try.

Damn I forgot my muse Hidaka Shouko and Yuuutsu na Asa http://www.mangago.me/read-manga/yuuutsu_na_asa/ but you will need to buy the last two volumes because it was licensed. Hana wa Saku ka is also a good slice-of-life http://www.mangago.me/read-manga/hana_wa_saku_ka/
