Help, pls.

Looking for a BL manga. I haven’t read it, so I’m not sure what it’s about, but in one of the panels, a kid proposes to a delinquent in an alley. The same kid also finds him beat up in an alley and cries about it. I think the kid gives him flowers. There’s a time skip, and that’s all I know. If you have any idea what manga this is, link me, please. Thanks!
