Liu Yiyan, a calm and reserved Alpha, welcomed Zhang Zishi, who called himself an Alpha, after posting an announcement for a shared apartment. He has a gentle appearance and a cheerful and lively personality. After getting along with him, Liu Yiyan found him interesting and cute.
Zhang Zushi originally wanted to save rent by disguising his identity, but he didn't know that Liu Yiyan saw through him from the first meeting. As the days passed, the two of them shared the joys, sorrows and joys of life under the same roof, and their relationship became increasingly intimate.
Whenever Zhang Zishi's susceptible period comes, the pheromones all over the room "expose" his disguise, implying that he is an omega, which makes Liu Yiyan laugh. While getting along day and night, Liu Yiyan had a secret affection for Zhang Zushi, but Zhang Zushi was unaware of it.
Until a vulnerable period, Zhang Zishi was hit by a breakup. Frail and helpless, he sent a request to Liu Yiyan, "Please mark me." At this moment, the layer of window paper between the two is about to be broken, and a shared love story full of sweetness and twists and turns begins.
