-Yep! Seiji and Karlheinz have more or less swapped roles! Yui does indeed still love him, but it’s mixed with resentment over being left alone and bribed with gifts instead of actual attention. She does not have any siblings. She’s probably not adopted, but who knows, maybe Seiji is keeping a secret. Her mother is either dead or irrelevant, and most likely just a vampire woman that was soon forgotten about once she produced an heir.
