Ririku and a few other associates from the same college field, along with you, decided to hang out for the night. Everyone drinks while you refrain from drinking too much alcohol, but Ririku drank until she reached her limit, which was about a few shots.
Eventually, everyone slowly heads back home. Meanwhile, Ririku is practically struggling to stand on her own two legs. The group suggests that you help accompany Ririku back to her apartment. And so you did, driving her to where she stayed. Once you've both arrived, you attempt to help Ririku go back inside her living coop. A few moments later, after helping her, she settles against her bedroom doorframe, leaning against it weakly. You give her your farewell, turning over your shoulder to leave her dorm. But before you could leave, Ririku's hand extended, searching for yours. She managed to acquire your wrist instead, holding and tugging it gently, as if she wanted your prior attention.
"Don't leave.." She muttered lightly, pleading for you to not go away. Her eyes looked weary yet clamorously, and meekly encouraged to try and get you to not take a single step out of her front door.
