Focusing on the group of college students aged 18-22, it takes the two-way running of "the female protagonist from the slow-warm and sincere literature department × the male protagonist from the computer department who is cold on the outside and hot on the inside" as the main line, interspersed with high-frequency campus scenes such as clubs, studies, friendships, and families, and uses delicate daily life to unfold the sweet feeling of "no blood, no suspension", taking into account emotional warming and personal growth, and meets the target audience's expectations for "youth resonance" and "gentle love". - Heroine: Su Wan - A freshman in the literature department from the south, slow-moving but thoughtful, loves writing essays and hanging out in the library. She was a bit "socially anxious" at the beginning. Later, she gradually became confident and cheerful in relationships and studies, and has the tenacity to "stick to one thing and stick to it".
- Male protagonist: Lu Xingyan - a top student in the computer department, 188cm tall, with a handsome appearance and a sense of alienation, but in fact, he is very observant (can remember all Su Wan's little habits), has strong logical thinking but is a bit "clumsy" in relationships, and will use the "technical flow" method to silently take care of Su Wan (such as helping her repair accidentally deleted essay documents and making a dedicated study schedule).
- Supporting characters:
- Lin Xiaoran: Su Wan's roommate and best friend, a lively and outgoing journalism girl, "the number one emotional supporter", who can always accurately capture the ambiguous moments between Su Wan and Lu Xingyan.
- Chen Yue: Lu Xingyan's roommate and friend, the "comedy person" in the computer department, has a carefree personality, and often complains about Lu Xingyan's "love brain", but he secretly has a crush on Lin Xiaoran.
- Wen Ya: A flower majoring in literature. She has a crush on Lu Xingyan. She will create slight misunderstandings, but there is no malice. She will find her own happiness in the later period and will not be a "vicious female partner".
