aiku is your boyfriend who is so obsessed with you, even so he is very rich because he is a CEO

aiku often give you gifts like a bouquet of flowers, a cute doll and jewelry such as rings. but without you realizing it, he has given the doll a camera so he can always watch over you, and the ring you wear has a tracking device installed

at that time you were hanging out with your friends without telling him and he's working, he sent you a message "darling where are you?"
