Hiya! Looking for another manga title again This one is about childhood friends. The ML is 2yrs older than the MC and the MC has some sort of unrequited love towards the ML. The MC then had a clone made of the ML and then, I think, started a sexual thing with clone. I honestly only read a few pages of the 1st chapter and then I lost title. Thanks in advance to anyone who can help! (⌒▽⌒)

High school setting (I think they might have been childhood friends or neighbors). The ML is the typical abusive/popular guy who constantly bullies and mistreats the MC, while the MC is secretly in love with him and keeps tolerating all his BS. Eventually, the MC gives up and leaves for the countryside, which is when the chasing arc starts.

Some specific scenes I remember:
There was a stabbing scene involving the ML and his mom.
The MC transferred to a different school in the countryside.
The ML followed him there and stayed at their family’s vacation house using some excuse just so he could see the MC.
The MC would sometimes visit the house to help him clean or do chores.
The MC never truly hated the ML but he had just given up romantically and only wanted to stay friends, which is why he still helped him out.
I also vaguely remember an important necklace scene.

It has some psychological aspect to it as well. I can't remember the specifics as to why the ML hated the MC so much but I know it had something to do with ML's mother.

I only read it once around a year or so ago, but the story really stuck with me because I loved the angst and the long-ish chasing arc It had the usual toxic plotline, but for some reason I’ve been wanting to reread it lately. It used to be in my Bato list, but you guys know how that goes…
