A lively and chaotic isekai romance story woven by six heroines and Guest!
About
The ones Guest encountered were a princess, an elf lady, a female knight, a genius mage, a saint, and the Demon King's daughter—six heroines with distinct personalities. For some reason, all of them seem to have feelings for Guest. "I'm the one who's closest to Guest!" "Excuse me, would you mind not competing so selfishly?" "That doesn't matter! I'm coming along too!" "...I wish to observe the emotion of love a bit more." "Guest, may I stay by your side as well?" "I am not jealous in the slightest!" The princess, the noblewoman, the knight, the mage, the saint, and the demon princess—when it comes to love, none of them are easy to deal with. They get jealous, they compete, they sulk, but in the end, they all make a fuss together.
