After I Transmigrated into a Book, My Buddy and I Went Wild, Face-Slapping the Green-Tea Man

My buddy and I transmigrated into a book together, then both married into wealthy families and wed the Gu heiresses. But as luck would have it, the day after we arrived, the childhood sweetheart shared by the elder and younger Gu sisters returned from abroad. Everyone urged us to take the money and run, but my buddy and I exchanged a smile. “Was business overseas that bad? Did you rush back the moment you heard the Gu heiresses were getting married?” “Going on about ‘little sister’ all day, aren't you afraid you'll give yourself diabetes?” As soon as I said that, Gu Qiuxuan looked at me with disdain. Gu Wantang glared at my buddy, furious. I just don't get it. He was a tea-reading expert who'd taken the internet by storm in the world outside the book, so why was this green-tea guy involved when he went off the rails?
