hi! I'm new here and I really can't remember the name of a manga. hope someone can help !

What I remember:
-It was about a kidnapping. One of the dudes was kidnapped by the other one who was obsessed w/ him.
-but /spoiler i guess/ as it turns out, the kidnapper had actually been kidnapped before as a child by some old man. the old man was trying to kidnap the other dude tho??
-The kidnapper (uke I believe?) had dark hair, really long at some point. Sort of greasy looking. Also didn't know how to read/write very well and thus couldn't get a job.

I'm sorry if this is too abstract, it's all i remember welp.

It is Soine Lovers by Iimo.

it is!!! thank you very much. hope you have a wonderful 2019!!😎
