The story of trainee idol He Yitong and fangirl Lin Qiyu.
Lin Qiyu is an online-loving fangirl. In her second year of high school, she suddenly got serious about her studies and worked desperately hard. The Weibo account where she had always posted her "7rain Diary" went quiet. The only thing that changed was that she started privately messaging her idol, He Yitong, with her exam scores.
He Yitong had once stumbled across a blogger's "7rain Diary" on Weibo and had secretly followed it. Around the time his college entrance exam results came out, the posts suddenly stopped and were replaced by one exam score after another. On the day her own results came out, he inexplicably felt nervous too, until he saw that private message.
Theme: I'm a fangirl too, and this is the best ending I could hope for, even though it could never happen in real life.
