The kind-hearted and warm-hearted Little Sun heroine × the infatuated, dedicated and possessive male protagonist (sibling relationship, 3 years age difference) Ji Zhiyu was born solo for twenty-five years and thought that the final result would be a blind date and marriage. However, because he went home during the National Day and chatted with his friends about the embarrassing things in the past, he pulled out that shocking boy from the depths of his memory. Sure enough, the boy she met when she was young was too amazing, and she didn't want to give in to those she met later if they couldn't compare to that guy. Meeting that beam of light in life again, Xi Boyan's heart was filled with excitement and his hands were trembling. When she fell asleep in his arms, he secretly decided never to let her go again. He would stay by her side no matter what method he tried. If the person he spent the rest of his life with was not her, then even leaving this world would be regretful. Dear Ayan, then we will be in love with a kiss. Dear Zhizhi, we can't let go when we hold hands.
