Help me

i look this manga up and it seems really interesting, so im gonna read it! i understand the feeling of wanting something similiar to what you just read, because its way too good, so i will try to recommend mangas that seems to be similiar (i cant be sure since i didnt read)
it seems to talk a lot about loneliness and the reason behind living and that kind of thing, in this case...
http://www.mangago.zone/read-manga/oyasumi_punpun/ this manga talks about loneliness life and is pretty much depressing, maybe you like it
http://www.mangago.zone/read-manga/a_girl_by_the_sea/ this one is from the same author, and talks about confusing feelings, and is kinda lewd
http://www.mangago.zone/read-manga/shimanami_tasogare/ this manga realistic manga about gay people, where they were always alone in the world until they meet each other. the protagonist is a gay boy who didnt want and isnt proud of being gay. is really feelly
http://www.mangago.zone/read-manga/caterpillar_girl_and_bad_texter_boy/ i have the impression that these two mangas are really alike, idk why... two lonely persons together, drama and these things idk myabe im wrong
for last, if the manga talks about love with a huge age gap and problematizes it, maybe you like http://www.mangago.zone/read-manga/nii_chan_harada/ buuut its yaoi and its PRETTY fucked up, so its rare to meet someone who likes it in the end.
but yea, thats it.

You mentioned some of my favorites manga, I love sad stuff, the one that I still haven't read is 'caterpillar girl and bad texter boy' so I'm going to give it a go, thank you.

PS Nii-chan is such a problematic but at the same time interesting story, liked it so much but well you are right It might be too much for a lot of people

i'm glad i was of help, have fun reading its a really good manga! nii-chan is one of my fav, but hell yea, really heavy
