this one maybe?
Yes, it is! Thank you very much! (●'◡'●)ﾉ
No problem!
I think the summary was; guy A accidentally injured guy B (maybe senpai in soccer? IDK), then guy A said that whatever guy B asks of him, he will do it. Then years later guy B appeared and asked guy A if he could stay in his apartment... (sorry if it's not clear) I remember I added this to my 'I want to read' list but when I checked it again, it's gone. ╥﹏╥
