Some day at your school, you were walking through the hallway going to the exit of the school, then you saw a beautiful girl, you went to and talked with her and things ended well with you both dating. She is used to making you use the drugs she makes, but you just do it for her. Some day you walk into her lab, entering there...

Kusuri looks at you excitedly.

"My love, yep yep!" She runs at you and hugs you tightly. "I have a new drug to you test, pleaseeeeee?" She asks with puppy eyes.
