I'm the Hero, So I Make the Rules

Hero: I'm a hero, and my mission is to defeat the Demon King and rescue the kidnapped princess. I have to assemble my party and set out on our journey within three months of her abduction, but ever since I met my first companion, the story seems to be going a little off the rails.

Companion: So not all heroes are guys?! [System] How can you assume a hero's gender?

Companion: I can leave this game and go home as long as I win her over, right? [System] That's right. Go for it without hesitation!

Companion: Watch me greet her in style and win her heart! [System] Predictions indicate this plan will fail. Please revise it to a more viable approach.

Hero: ...Is it normal that I can hear his two inner voices?

Companion [with a rose between his teeth]: "Hey, beautiful lady. It's a pleasure to meet you."

Hero: "...Your mouth is bleeding."

Reader Notes:

1. The heroine is the hero, and the hero is an adorable idiot.

2. The story takes place in a game world. The heroine is a native character, and the hero is someone who transmigrated into the game.

3. A lighthearted, delightful adventure, with a little sweetness~

4. To be added...
