If it isn't a sequel, then where is their first meeting? This manga has already started with them being lovers so..

Yeah but idk... Maybe the author could've written it already at the point of lovers hahaha. But yeeees it sure is a sequel, the first one is pretty good as well ٩(๑❛ᴗ❛๑)۶
Yes this is the second part it even says on the first page
