How do he know that string is mean to be connect to your fate partner ?
Maybe its actually link you and your destiny 5000 ton giant robot hidden somewhere ? Who know ! Maybe try to follow it to find out ?
Well...if he can see such things for a long time, I guess he already have seen people who already met up with each other. And he still doesn't believe it...
I'm loving this premise. A love that defies fate. I actually think their red strings will eventually be tied to each other and I like that idea. Sometimes red strings can be cut or tangled or even retied to someone else and it all depends on your how you interact with others. I can't wait to see where the author is going to go with this.
