Hey! Don't Touch My Hair!

Two male protagonists, 1v1, quick travel? Infinite world? [To be determined, I will change the introduction after I write a little more] A long time ago, there was a little liar. He heard someone say, "When my hair grows to my waist, you can marry me." He thought this sentence was romantic, so he gave it to another person, and then he left. The man waited and waited, until the little liar floated away in the wind, and until his hair became longer and longer. Later, he knelt in front of the stone and asked, "Why don't you come and marry me?"
