Help looking for manga! TW selfharm

I'm looking for a bl manga that's stuck in my head but i can't find it. It is set in a small town, where Character A lives and works. He works at a convenience store. His dad was abusive and went to jail for it, but there's only about one month left till he gets back out. Character B meets A in the conbini and ends up eating there every day, always just a small ramen. A gives B onigiris because he looks hungry. B doesn't want them but takes them anyway. They build a friendship because B asks A to show him around town, because he is new there. (TW Suicide) B only moved to the small town because he is looking for a place to die without being found. I think he has an abusive family, he took some money and keeps it in a suitcase. The relationship develops really slowly. Hope someone knows the plot, and can tell me the name. I would be so thankful!!
