After losing my husband when our son, Gaku, was still young, we have been living together as mother and son. As Gaku approaches his 20th birthday, he increasingly resembles his father, bringing both joy and sadness as a mother and woman. On the eve of his 20th birthday, we shared our first drink together. Although I am not a heavy drinker, the alcohol tasted particularly good that day, and I ended up drinking too much. Gaku, also tipsy, became unusually affectionate towards me.
