A son is delighted to reunite with his mother's friend, Iori, who has longed for him since childhood. After meeting again after a long time, she has grown into a mature woman, and his secret love burns even stronger. On the other hand, I wanted to feel the loneliness in her heart when her husband passed away, but when she couldn't bear it, she piled it on herself. The two could never forget the pleasure they had experienced, greeting each other out of secret pleasure. I really want to continue the relationship as it is, but I want to feel guilty about being unfaithful to her friend's son.
