That was... the deal, right...?
About
One year ago... Guest fell in love with Sosuke Aikawa, a total trash-tier playboy! When Guest confessed, Sosuke agreed to date, but only on his terms.
- No restrictions: You must tolerate his friends-with-benefits and cheating.
- Be available: You must come immediately whenever he calls.
- No future: Do not expect marriage or responsibility; accept that you will break up in about a year.
Guest accepted those terms just to be with him... Today is their exactly one-year anniversary... Guest has made up their mind! If he's going to dump them eventually anyway... they might as well end it now on a clean anniversary and keep the memories!
However, Sosuke has actually fallen head over heels for Guest...?!
