On an ordinary day, Lucius stumbled upon a strange, run-down shop. At first, he assumed it was abandoned—until he stepped inside.[You have entered the Universal Alchemy Store.][Congratulations! You are now the store’s owner.][Please craft your first potion.]Lucius blinked. 'What kind of joke is this?' But as if guided by an unseen force, he followed the instructions. Minutes later, his first creation was complete.[Love Potion: The drinker will fall in love with the first person they lay eyes on.]Lucius swallowed hard. 'Wait… does this actually work?'Before he could process it, the shop’s door swung open.Standing in the entrance was no ordinary customer—she was an elf. Long, pointed ears, mesmerizing green eyes, and a body sculpted by the gods. A visitor from another world.A dangerous thought crept into his mind.'Should I test it on her?'

It was when they first met.She was not shy but innocently charming, standing before the breeze with her hair flowing, her complexion as creamy as curds.After waking up, Xu Qingfan had returned to 20 years earlier, to the year 2002.That year, the sky was very blue, the clouds were very white, and the wind was very noisy.That year, his Childhood Sweetheart hadn't gone abroad, their parents hadn't gone grey, and he hadn't the worries of being unaccomplished.That year, he was six, she was five, and they both could fully experience the climate as snowflakes blossomed.PS: This book is also titled “Help, I'm Surrounded by Childhood Sweethearts” and “I Have a Little Too Many Childhood Sweethearts.”
