The first book is a quick time travel type. The first plane is Voldemort, with a normal appearance. The male protagonist is pushed down at the beginning but counterattacks. Lao Fu tries to counterattack in the second plane, but is coughed again. The second book is that Lao Fu returns to normal in the end. The whole process is funny and the pace is very fast. The third book is a CP with Riddle in the diary. The woman loves the man. Both strong and clean and sweet and non-abusive. Riddle is marked by the female lead (marks each other). In short, both of them love each other very much, which is very sweet.
