Graphic violence is specifically, any graphical violence such as blood, gore, etc. Is it violence? Yes. Graphic? No.While I agree with everything you said prior to this and this in most cases, not every game lists planned tags or every tag available in the game. Artemis has what is technically graphic violence in it (bear fighting a dog and attacking Kindra, the douche during the Zelda date, also multiple scenes involving Cassandra), and it isn't listed. Honestly with how close and open some of the girls are, the game sort of screams harem, or at the very least a poly relationship. May just be hopium though.
I would love to see some of the girls at the same time. But I appreciate the reality that having to choose a love interest brings to any game. There are some harem games that get so ridiculous at not choosing a love interest that it hurts the story significantly.
