Searching for a BL manga, I remembered all the details but I forgot the name and want to reread it!

The bottom in question is a single father (divorced but still get along well with his ex wive), he owns a run down sweet shop that was passed onto him. When his daughter got sick, he went to the doctor and that was the top! The top was only there in his grandfather, I think or is it his father?, stead cus granpapi got hospitalized.

The top looks ur typical scary dude but is actually really green all around! He came out to the bottom as gay pretty quickly and confessed to being interested in the bottom.

In one of the chapters, they went to the beach!

It ended with the bottom telling the top, "well my marriage with my exwife lasted *this many years*, so if we're together for more than that, I'll consider this Official" or smth along those lines!
