When I was 7 years old, the boy caught a cicada, thinking he had captured the whole summer;

At 13, he held the girl's hand, believing they could be together forever;

At 21, the boy dropped out of school to work, while the girl had already blossomed and enrolled in a prestigious university. The boy thought to himself, he must be worthy of her in the future;

At 28, the boy learned to trade cryptocurrencies, buying low and selling high, thriving in the market;

The next time he saw the girl was in Dongguan, in a dimly lit room. The girl spoke first: 998, since you're a familiar face, I'll charge you 888; the boy grabbed the girl's hand: Come with me, I will marry you;

The girl gently smiled and said: Sorry, I have other guests;

The last time he saw the girl, she stood on the rooftop, asking the boy: I have a terminal illness, and before I go, I just want to ask you, do you still love me?;

The boy's voice trembled: Yes, I love you. Let me get back on my feet, and I'll take you to get treated;

The girl asked: What cryptocurrency did you buy?;

The boy replied: ETH.

As soon as he finished speaking, the girl jumped down without hesitation.
