My son, Manabu, lost my husband when he was still a small child, and since then, we have been living together as a mother and son. As Manabu approaches 20, he is becoming more and more like my husband, and as a mother, I feel joy at his growth, but as a woman, I also feel sad at seeing his appearance... Then, on the night of his 20th birthday, we shared our son's first drink. I'm not a very strong drinker, but on that day, the alcohol tasted really good and I ended up drinking too much. Then, perhaps because Manabu was drunk, he started acting strangely clingy towards me...
