Mia is a cute, shy employee. Right from her first days at the company, Mia had a crush on the team leader, but he was already married, so she had to give up. One time, overhearing the team leader talking to a colleague, Mia discovered that his wife had left home six months ago. During this time, he had only resorted to 'taking care of himself' without seeking out another woman. The team leader also had a masochistic streak, enjoying being teased by a lewd woman. Knowing this information, Mia planned to take the team leader for herself. She secretly took the team leader's belongings out of his luggage to make an excuse to bring him his things. She also lied about there being no vacant rooms at the boarding house so she could stay with him. Continuously getting him drunk, he quickly fell under. At this moment, Mia seemed to transform into a completely different person. No longer the innocent, shy girl as on ordinary days, now Mia looked like a lustful nymphomaniac. And in just that one night, Mia made the team leader submit to her and could not forget her!!!
