I LOVE THIS MANGA!~ If you're looking for a yandere/possessive/obsessive ML then this is the perfect one!! (i know that sounds weird and i have a very questionable taste. forgive me.) Anyway, at the time of writing it still only has 6 chapters so it's too early to be in-depth, but so far I really love it. Basically, FL is the granddaughter of a yakuza family and has our ML as her over-protective guardian ever since she was young. It's really cute because now that FL is in highschool, she tries and does things by herself without the help of Iori (ML) and that reallymakes him mad, hence his yandere tendencies~
