第一次初遇，其實是我們第一百次相遇！ 當疫情蔓延封城之際，只剩下頂樓和陽台能夠呼吸新鮮空氣。一天，雨霏巧遇對街頂樓新搬來一名俊帥的男孩逸書，對他頗有好感。很快就答應逸書的頂樓燭光晚餐之約，隔著一條街，兩人對坐頂樓，舉杯搖曳在璀璨的夜景裡。 雨霏以為是初遇，但對逸書而言，已是第一百次邂逅！原來，雨霏患有短暫失憶症，每一天醒來就會忘記昨日的記憶。逸書卻不以為意，願意為她創造每天的驚喜。 對逸書而言，雨霏彷彿是苦悶生活的寄託，有時，他會注意到對街陽台的雨霏戴著耳機忘情搖擺的可愛模樣，或咬著筆陷入苦思情狀令人心疼。他會假裝外送員、水電師傅、傳教士，故意接近雨霏；然而那一次頂樓的相遇，則是他假扮成新搬來的男孩。 一次逸書想製造巧遇，卻意外發現雨霏是心理諮商師，原來真正生病的其實是自己。一切都是雨霏不敢戳破的幻象，只為了陪伴逸書治癒他的心理疾病。但是逸書不知道的是，當他闖入雨霏的生活那一天，她早已悄悄地愛上他。

Our first meeting is really our 100th meeting! At the point of quarantine during the epidemic, the only places left for fresh air in the city are balconies and rooftops. By chance, Sophie meets Isaac, a good-looking new neighbor from the rooftop across the street. She finds herself attracted and quickly agrees to Isaac’s invitation to a candle-lit dinner. Separated by a street, the two sit on separate rooftops and toast their drinks in a beautiful night scene. Sophie believes that that is their first meeting, but for Isaac, this is their 100th encounter! Sophie has short-term amnesia: When she wakes up, she forgets about everything from the day before. Unperturbed, Isaac willingly recreates their meeting everyday to make her happy. For Isaac, Sophie is the antidote to the tedium of daily life. Sometimes, he notices Sophie on the balcony, wearing headphones and swaying adorably, completely un-self-conscious. Other times, his heart aches watching Sophie chewing on her pen while struggling with her thoughts. To get close to her, he has pretended to be a delivery boy,a contractor, a missionary. When they meet on the rooftops, he pretended to be a neighbor who has just moved in. During one of his attempts to recreate their first meeting, Isaac discovers that Sophie is really a psychologist, and that he is the one with a mental illness. Wanting to stay with him and to try to heal his psyche, Sophie doesn’t dare shattering Isaac’s illusion. What Isaac doesn’t realize is that, on the day that he stumbled into Sophie’s life, she had already fallen for him.
