One day, she spots him walking intimately with a younger female colleague.
Shaken, she tries to dismiss it as a misunderstanding, but the seed of doubt takes root, and while Daiki is away, she gives in to temptation and checks his computer, only to discover undeniable photo evidence of an affair.

Just then, Daiki returns home… with the woman.
