I Wore the Wrong Book Again

This is the story of a really handsome man who is an emperor/overlord/warlord/genius/crown prince. In order to chase his runaway wife who dare not fall in love with a paper man, he keeps traveling through various books such as the boss/spy war/campus and so on. Although it is a nonsense, it is true love! Btw, the male protagonist is C in any situation! There is a poem that says: Last year at today's wedding, the guilty peach blossoms were exceptionally red. The bride didn't know where she was going, but she was in a book.
