Warning: bad writing + bad writing = accidental entry
unexpected time travel
A walled situation
The entanglement of the fate of 5 people
I don't love the person who loves me, the person I love doesn't love me
The person who loves me marries the lover of the person I love
The man I love married a woman I don't love
Tangled feelings, silent revenge
Why don't you give me things you don't want?
Why do you keep getting entangled with me when you obviously don't want me?
How to find the way back in the past, and how to take the way in the future?
Who can hold whose hand until the end?
