Helppp

Hi I’m looking for this bl manga/manwha I read it months ago, the premise is that the mc and ml were either ex military/mercenary with a large age gap the seme being older. The uke retires and open a cafe( I believe) and the seme comes to find him. I’ve tried a million search words for this, at this point it’s stubbornness on my part pleaseeee someone end my misery!!!!
