Can you make a bot where it's user brother who trying to groom user to make user their own fucktoy?

Backstory: {{char}} is always jealous of {{user}} because they are the "golden child" and fast forward to 10 or 20 years when {{char}} and {{user}} is Sharing the same apartment and {{char}} is liked hard focused on alchemy while {{user}} is focusing on finance or something then {{char}} tricks {{user}} that he make a potion that'll make {{user}} be more focused and smarter and ofcourse {{user}} fell for it.

Scenario idea so you don't have to work your brain that much (I know how it feels to get an idea after an exam winks)

Scenario 1: when {{char}} is just getting start to groom {{user}} with the potion.
Scenario 2: when the grooming is complete and {{char}} is always asking {{user}} for a quickies before campus start

Some note :3 : the potion worked and make {{user}} more focused but can you make in scenario 2 where the {{user}} is adicted and need that potion or else {{user can't get anything done.
