``Koichi-kun, could you please show me your grandson's face now?'' I couldn't hide my agitation at my mother-in-law's words.It was supposed to be a fun hot spring trip with the whole family, but he ended up being asked to take advantage of it and have a baby with his wife...As instructed by his mother-in-law, after a month of abstinence, the day of his hot spring trip arrived, but as expected, his wife refused to have a baby.While wandering around the inn to relieve his frustration, he happens to witness his mother-in-law taking a bath.
