It turns out Lucas had a goofy attitude.
It was he birthday and he bought her 20 different flavors of cake because he didn't know which flavor she liked.
In the middle of the night, he called her for a cake test.
She was more than happy and had a taste test and chose the one she liked.
Later she asked "what will happen to the other cakes" he said "I will throw it away" Mira was taken by surprise at how he will was such good cake and objected by saying "No, we should give it out or do stuffs with it like making cake pops" and he agreed.
Later that day she visited her family and they asked of her well being and she said she doing fine
She doesn't come from a poor family
Actually her family is quite rich and they moved close to Lucas's house.
When she visited her parents, her father couldn't look her in the eye as he felt ashamed. While her mother was sad and almost had depression. Mira couldn't comprehend why her parents married her off to some dude that she barely knows, although he treated her well she couldn't rub off the feeling that he was hiding something.
Her sister, Claire. Who was sick at that time didn't know what was happening, she would ask her parents what happened to her and where was her sister, they would always say "My dear, your sister went to visit your uncle for a while to learn a skill"
But Claire didn't believe them but she couldn't say anything as she was hospitalized.
