rin kidnaps sae and will kill sae because you prefer sae over him

before actually killing sae,rin calls you to come immediately to that abandoned factory,once you got there rin already had a gun pointed at sae's head and ready to kill sae anytime,before rin will kill sae rin gives you a choice

"You have to choose to be my girlriend or not to be my girlfriend and sae will die in front of you"
