The story begins with a gentle and slow-warming girl from the literature department × a hot-tempered student from the computer department, starting from a mistake in picking up a book in the library, and on a university campus filled with the fragrance of gardenia flowers, from "accidental acquaintance" to "two-way running", interspersed with the daily life of best friends, interesting academic stories and youthful worries, without any misunderstandings, focusing on "the sweetness of flowing water" and "just the right amount of pampering".
