SAN-111 The friend of my ex-husband is an old girlfriend from college. Opening the Pandora’s box that shouldn’t be opened, she fell and became even more conspicuous as a tall married woman Yui Takigawa.

Naoki, a mutual friend of the Yuina couple, has divorced. The two visited Naoteru’s house to encourage their heartbroken friend. When the three of us were having fun drinking, the husband of Yuina, who has a weak drink, fell asleep. While drinking with two people, Yuina, who is weak against pushing, is swept away by Naoki and crosses the boundary that should not be crossed.
