This is a story about growing up and a love story about waiting. The so-called waiting is not waiting for the arrival of a certain person, but waiting for a suitable love. Tianlei guarantees that there is no such thing, but there may be some. The love fairy tale between the uncle and Loli is both warm and cruel.
Tangyuan'er often regrets that it was because of someone's coquettishness that she missed the opportunity of puppy love. Every time she heard her complain, someone would give her a kiss, and all the complaints would disappear in an instant. But Tangyuan'er never told someone how lucky she must be to be able to meet him and the love of her life in the most beautiful years; and someone never told Tangyuan'er that the love he thought had actually started the moment he met her.
