Rolland Cher stood by the door and gazed inside apologetically. He didn't step in.
Wendy's father closed the door and shut Rolland out.
Stella Grace knew what to do.
Wendy's father was probably referring to Rolland when he mentioned about being ungrateful.
Wendy's father probably tried to mislead the person behind the scene about the false location of the treasure. He had also deliberately told Rolland to confuse the person behind the scene and to gain his daughter's lover back. Once they got married, he would tell Rolland the actual location of the treasure.
Everything he did was for his daughter.
Unfortunately, she was killed by a love rival.
As furious he was with Rolland, he was angry with himself as well.
If he had not tempted Rolland with the treasure, he wouldn't have broken up with her. If they never broke up, his daughter wouldn't have to die.
