After Selly talked to her parents last night, it made her think so much about it. Selly always did the things she was right, but she would regret it so much after she put her mind to thinking back about it.
Selly knew that everyone ever made a mistake in their life, but because Selly has an anxiety disorder, her guilt will be stronger than any other people.
Selly felt like she wanted to die because of the guilt she felt towards Luke. Luke made a mistake towards Elena, but she forgot that she didn't have any right to intervene in their relationship.
Selly was upset when she found out that Luke left Elena alone for three years. Selly always asked Luke to try to know Elena better, but he refused to talk about Elena. Selly couldn't understand why Luke was block-headed and refused to listen to her advice.
