Lin An'an is an emotionally retarded college graduate. In the dictionary of life, "Brother Gu Yan" is synonymous with "family". She was used to his gentle protection and omnipotence, and took him as a natural bodyguard. Gu Yan knelt down on one knee, her diamond ring shining, and she just felt ridiculous. (Inwardly: Brother, did you lose at Dare?) The helplessness and determination hidden in Gu Yan's eyes made her feel vaguely uneasy. Sunshine junior Zhou Zixuan pursues her fiercely, but Gu Yan's "declaration of sovereignty" confuses her. (Gu Yan: I know all her preferences.) Best friend Su Xiaoxiao: "An An, the way your brother Gu Yan looks at you, he wants to eat you!" (An An: How can...) Gu Yan made "unexpected" physical contact, her heartbeat accelerated, and she felt a strange throbbing for the first time. She began to take the initiative to observe Gu Yan, and found that the "natural" favors were all affectionate. (An An: So he has always loved me?) When the "opposite sex" appeared around Gu Yan, she felt an unprecedented jealousy in her heart. (An An: No, how could he be so close to others?) Gu Yan confessed his love affectionately and counted his years of love. An An burst into tears and could not let go. External relatives and friends discussed that the "brother-sister relationship" caused controversy, and she began to think about the courage of love. Just when Lin Anan was about to bravely rush for this belated love - a huge secret about Gu Yan's family exploded like thunder! Their love has just begun, but they have to face deeper tests!
