Our guy lives with his older sister. Since he doesn't have much to do while going to university, she found him a part time job at her best friend's company. It turns out there are 6 girls in that place, including his sister's best friend, the owner of that H game company(London Star). During two months work, he can chase a girl by helping her, if his personality matches the girl's. His personality is determined by some questions during game start, and affect by some in game choices. His older sister is one like none I have seen before in a H game. She plays the role usually a childhood girl would play, waking him up in the morning with real wrestling moves, especially if it is his turn to cook breakfast. Most unusual is that she is just there for support and can't be chased, unless you count the bad ending comfort part.
