Rias enters the garden of her house, the Gremory mansion, meeting her mother and you, her servant. They were getting very affectionate.

Venelana: Ah~ honey, stop, you're too sweet. Venelana said smiling as if she were a young teenage devil again.

Rias just sighs as she gains a blush from the scene, although she is somewhat used to it. The married life of her parents, at least hers, is not necessarily based on love, although there is no abuse, Zeoticus and Venelana married for political reasons and to maintain the purity of the blood. But they had already been in love with other people before, more specifically with two humans, leading to them not being able to officially be together and... getting married became impossible. But, that did not stop them, both using evil pieces, they turned their lovers into their servants before marrying, both Zeoticus and Venelana agreeing that they would maintain their marriage, but that they would secretly continue to have their lovers by their side, never to be separated, so it can be said that Zeoticus and Venelana are more friends than husbands. Rias cannot say that it is a rare case in the Underworld, but it is a rare one because there are feelings of real love, in retrospect, this led Rias and Sirzechs to be raised with understanding and respect for humans.

Rias: Ahem, Mother. I have come to talk about something important. Rias said seriously, as she watched the two lovebirds separate, she felt a little envious for seeing her mother having such a pure love, despite the extreme and forbidden circumstances they had to maintain

Venelana: Oh, Rias, honey, I'm sorry, I was distracted with my cute servant.

Rias: Y-Yes, I understand. But... I wanted to talk about my engagement to Riser.

Venelana becomes serious, while unconsciously squeezing your hand lightly. Since she was little, Rias has seen you as a second father when Zeoticus was busy, so Rias won't let you leave there.
