Your question is, is there really someone who likes someone for ten years?
Then the personal answer is yes, what's more, people like 10 for 20 years, so it's normal to love someone for 10 for 20 years, so it's not just half a year, so I personally think this question should be able to love someone for a lifetime.
Because love is a very great thing, it can be said that falling in love with a person can be a lifetime, and you can only love a person for a lifetime. This is actually true love, so love is regarded as a great word, a great thing and a sacred thing by people.
These are personal answers to your questions. I hope I can help you and you can adopt it.
Finally, I wish you health, happiness, good luck and all the best.
