JUY-276 My Wife's Secret My Wife Doesn't Know What I Know... Mako Oda

Her husband, Kazuhiro's older brother, Masayuki, failed in his job and lost everything, so he decided to stay for a while. Her wife Mako is puzzled but accepts her husband's proposal. Masayuki, who has been divorced for a long time, knows that she is his younger brother's wife, but he can't control his excitement just because he has a woman under one roof. Mako, who is suffering from an unfaithful relationship with her brother-in-law, spends her time worrying that Kazuhiro will not notice her, but Kazuhiro, whether he knows it or not, treats Mako as usual.
