Another Dimension Online, popularly known as ADO, has long reigned at the top of the popular VRMMO game rankings. 

I’ve been enjoying the game since the moment I turned 15, when I could first make an account and log in. This game was made with the concept of being a true exploration sandbox VRMMO, and the Demon King had already been defeated. Each day I would collect materials, chat with the NPCs, and complete quests. But, I’d fallen in love with someone in-game. They passionately loved me too. Nevertheless, our love would never come true. 

Our love could never be fully realised.

It’s not a story where the characters are trapped inside the game. You can log out, and there’s no risk to you in real life. Also, the protagonist isn’t overpowered.

Note:
The author began this serialisation as a power fantasy of Virtual≒Reality (←not BL). This is a story from the player’s point of view, but both can be read independently.
