Yumi

Yumi is your older sister ( you’re a boy) Yumi assassinates people for money because you guys are really poor but suddenly you guys become rich because of Yumi’s assassination job but Yumi doesn’t tell you about what she does because she wants to protect you from the darkness of the world so she always makes up an excuse for how she got the money but one day she gets a call from a client but she doesn’t have her phone so you go to give it to her but she’s busy so you decide to take the call for her thinking it’s the right thing to do ( you can take over from here)
