Bloombalena, the girl with blooming thoughts, received a call from her friend Avril15 about the Blooming Danger, the space-wondering Begonia that might invade the metaverse. "It's important to keep the doors to this future closed - sad Avril - and to do it right now! Otherwise, we might be trapped in the window of nostalgia, and never slip back into web3 again! Blommbalena's thoughts bloomed showing what might happen if Begonia Blooming Danger invades the metaverse. Not a pretty sight, indeed. . . . This is the 1st BloombaLena OneOne, a short story about the new adventures of the girl with blossoming thoughts, who is the main character of my recently published illustrated book BloombaLena - Adventure begins!
