[Mutual Firsts + Secret Crush + Married First, Love Later + Sweet Romance] On the day she tried on her wedding dress, Li Qingwu was abandoned by her fiancé, who went to keep his one true love company. Standing outside a private room, she saw with her own eyes as he flirted and confessed his feelings to that woman.
