A little ray of sunshine named Lin Xiaoyang joins the planning department at Xingtu Media. On her first day, she is struck by the professionalism of Gu Yan, the director of the technical department. But Director Gu is famous as an icy workplace queen: taciturn and cold-faced, he even turns red at the tips of his ears when handing someone a document.
Their work coordination on the "Online Music Festival" project brings them together. Lin Xiaoyang goes from admiring him to falling for him, then, once she recognizes her feelings, launches straight into pursuit mode. She makes a blunder with homemade succulent fertilizer, orders a heart-shaped flowerpot and gets watched by the whole company, and tries to use work as an excuse to invite him to dinner, only to be turned down with an excuse about "feeding the succulents"... Her pursuit leads to no end of mishaps, but she also discovers the thoughtfulness hidden beneath Gu Yan's cool exterior: he remembers how sweet she likes her milk tea, quietly fills in missing details in her proposal, and even stands firmly by her when she is framed.
With her sharp-tongued best friend Su Man cheering her on, her buddy Lu Ze's spectacularly unhelpful assistance, a scheming coworker stirring up trouble, and a gentle love rival making an appearance, this hilarious and sweet pursuit of love sees a little ray of sunshine melt an icy heart. In the end, Director Gu's formula for finding love comes up with the answer: a love that goes both ways.
