When love runs deep, both people end up hurt! + Inspired by Shui Da's 188 series] [A preview] “I...,” Cheng Yan said, finding it hard to bring up. “If you have something to say, just say it.” “I'm actually a top.” “...” “I don't have any experience with the other role.” “You've never been a bottom?” “Right!” Cheng Yan nodded, resigned to it. [General outline] There are two volumes in total. The first volume mainly follows Cheng Yan as he unknowingly becomes a stand-in, while Gu Beijin falls in love without realizing it. Everyone around them keeps Cheng Yan in the dark, until he finds out for himself. The truth is a devastating heartbreak. The second volume mainly follows Gu Beijin as he tries to win his wife back, using every means at his disposal and vowing to get Cheng Yan back.
