I think them in a regular full chapter manga, not just short chap story ┗( T﹏T )┛. I need their backstory, like how they met, their childhood times, the days of them dating before they became mates, maybe also their future; like maybe them with their babies(▰˘◡˘▰). And also do you guys have recommendation with the couple dynamic like them (Clingy Puppy Top x Tsundere Cat Bottom)???
