MIMK-015 Dad's lover...

JULIA plays the role of a young tutor who teaches at home for a lazy boy, who is not diligent in his studies as per his parents' demands.

However, nobody is perfect; gaining one thing means losing another, so even though she is a very good tutor, she has the flaw of being a sex addict.

This is quite understandable as she has been divorced from her husband for a long time, and at her age, not being able to have relationships feels very uncomfortable. The boy is no better; he is weak in studies and often engages in playfulness, so when just a few minutes into the lesson, the tutor makes a sexual overture, he simply enjoys it calmly and responds.
