He was left alone. Then had pets and saw them die. Saw the 1st friend (a girl) die. Now this ant girl. This looks like he is slowly surrounded by girls like in harem genre but none of them are real (A. K. A AI). Its like you can see the most delicious food in front of you when you are hungry but can't eat. That's how mc craved human interaction đ˘
