As the topic said,
A manga which a male protagonist live alone / have no friend / lost his parent etc.
and should have some romance.(if it can be provided)

Something like Sangatsu no Lion.
Please be Shounen/Seinen.

Thank you very much for your recommend. >_<



________________

Homunculus

he lives alone[in his car]
he knows some ppl that he talks to...its not like they are his friends
and there is romance in a way

Wolf Guy - Ookami no Monshou
Vinland Saga (at least for the extremely long protologue)
Yuutai Nova (sorta....)


This should be enough for a couple days
Also, there is a novel that i think fits this if you want to read it:
Sword Art Online (Novel)

>_<

Thank you very much!



Haha I guess that's right~
