Part of why Suma was so quick to steal her sisters man was because she absolutely hated her sister. Like she made her life hell for no reason other than being a bitchy spoiled brat. Suma first of all genuinely liked Tengen, and second of all didnt want him to be with a pos like her sister. Suma and her family dont get along well at all really. She was never good at fighting like she should have been and she cried too much. She was too sensitive and she was annoying. She simply wasnt the child they wanted, and she wasn't the one they wanted marrying into a very high status
