I saw the raws. And based on google translate, Leo confirmed that there is really a vampire in Giselle's house through smell because they have unique smell. Also, they wanted to take Isaac to their house because they share the same blood and they own him. I read "house management and Oliver". Giselle denied it all because she didn't want to lose Isaac. That's why Olivia went to Giselle's house and took Isaac forcefully, though she didn't succeed. But, she was able to stab Isaac in his heart :< The latest raw was about Isaac and Giselle doing it again and Isaac telling her where he got the wound.
The ML looks like he was going to fall in love with her in a short period of time. ヾ(❀╹◡╹)ノ~
