Forever won't take as long with you (смешанная)

Shen Qingqiu misses Luo Binghe and his harem misses him, so they do the only thing they can think of.
Set post-canon in my Shen Qingqiu Harem AU where Cang Qiong Mountain Sect no longer exists, Shen Qingqiu runs a school and his system is requiring him to collect spouses like trinkets, forcing him to figure out how to juggle so many husbands (he's straight, he swears!) and Qi Qingqi (how did she get here?) while the protagonist, Luo Binghe, does everything within his power to climb into his pants. Follow Zhuzhi-Lang, a snake demon who can barely accept a compliment, as he learns how to seduce a harem master. Can he overcome his self-image that lies somewhere in the abyss and remind their husband that he isn't alone, or will it be too much for him to handle?
