An Old Man and an Old Man

A story about a middle-aged man who has taken up residence in the home of another middle-aged man approaching 40. Warning → I intended it to be more than friendship but less than romantic love, but since there are some BL-oriented expressions, I guess it technically counts as BL...? I'm not entirely sure, but since there's a setting where he had a wife, I'm categorizing it as romance. There's no sexual contact or mouth-to-mouth kissing. However, I believe that when someone is truly suffering, having someone by their side to support and be supported by is a relationship where gender doesn't matter at all.
