Taking My Wife and Kids to School with Me

Han Shuo transmigrated into a book, becoming a high school student in the 1990s. However, he has a chance to return to his original world, he just needs to complete the tasks in the novel.
Task 1: Find the key character in the story and kiss him 100 times, with a total duration of 365 hours, to unlock the return to the 21st century.
Finally, after much effort, Han Shuo found the key character, who turned out to be the top student at the same school. However, what he didn’t expect was that the top student was also someone who had transmigrated into the book, and he also had a kissing task.
In order to return to the 21st century, the two straight guys had no choice but to comply.
But when they had kissed so much that their lips were almost chapped and finally completed the task, they still didn’t return to the 21st century.
Han Shuo: Didn’t they say we could go back after kissing?
Top Student: It seems like there’s a second task in the novel.
Han Shuo: What task?
Top Student: We also have to… do it.
Han Shuo: To go back, I’ll do whatever it takes!
Task 2: Do it with the key character 50 times, and each time must last no less than 30 minutes.
But even after they finished, they still didn’t go back…
Han Shuo: What other tasks are there!!!
Top Student: Ah~ It seems we also have to have a child…
