Sharing the same fate
Warming your heart
So good, you even forget about manners
So much to learn
And yet happy

After such a long time
How Ironic
Tough Life of a Knight... or Thief
A thief's background
You better listen to the maid
Quid pro quo
Someone has to help, right?
Or a loyal act
Is this... A dream?
