Since Masamasa lost his father at an early age, Ying and Masamasa have lived together for a long time. Masamasa became more loved as a mother than aya who loved me with all one's heart. Masamasa, who graduated from university before long, got a job, but his place of work was Kansai. The invitation of the hot spring trip was invited from masamasa who did not want to part from mother. Masamasa decided to confess his thoughts on this trip.
