Traveling Through 86, I Am Forced to Open My Business

Classmates were chatting among themselves about whether there is a girl they like. You have just time-traveled, so if you don't have it, it doesn't matter. The protagonist has to say that there is, and also mentions the dormitory number of his ex-wife who did not travel through time (and also said that this is the only world where his wife in the previous life is still a child?) Then go home and tell your parents that you want to sing downstairs in the girls' dormitory and ask them to help? But you don't even have a goal! I thought it looked good but suddenly I was confused. How come the protagonist is sure that the one he likes is in the girls' dormitory? Can't be a day student, can't be working, can't be a teacher? How does the protagonist know? Did the author tell him? What do you think? It looked good but suddenly I became addicted.

The first few chapters were okay, but for no apparent reason, he appeared in front of others and brought out a lot of things that were beyond the times.

Author I like to see the author write about development and entrepreneurship 😭

It's not very eye-catching. The author should consider writing something he is good at. The description of family and relationships is a little tasteless.

You are reborn as a rich second generation, and you still have a golden finger. How come you are so invincible? Destroy the earth with one punch?
