I am looking for a manga beast shifter yaoi where MC is a beast shifter and in love with ML but he refuse ML becuz ML's family was murdered by beastman/shifters when young so he became a beastman slayer and MC thought ML will hate/kill him if he found out. And apparently MC has an older brother that works w/ a yakuza guy/lover. I can't seem to find the name! Please Help!I really appreciate it(づ￣ ³￣)づ

So am desperately looking for an Isekai shojo manga which I am pretty sure it's anthology one-shot stories where FL was accused of being a Villainess so her engagement got called off from the crown prince and ended up marrying to another country's cp or king. Soon afterwards ex-fiance's kingdom came to ask for her help/protection and she insisted she can help only if he answer all her questions truthfully for each right answer she will protect a piece of His land therefore not only did she got her name cleared but ex was able to find out the truth that all rumors about her was false.
