My Childhood Friend Luo Tianyi

Zhao Luxian has been reborn.

When he opened his eyes, he found himself lying in a kindergarten bed.

Then he realized something about his rebirth seemed off.

Not only does everyone in this world have brightly colored hair, but what do you mean his childhood friend is Luo Tianyi? What do you mean he also has a “boyhood friend” named Yanhe? The girl next door, Mo Qingxian; his elementary school class monitor, Yuezheng Ling; his online wife, Kagamine Rin; the gamer girl Shian... The songstresses who should only exist in a virtual world have appeared in reality, in all their varied forms.

The only one missing is... the world's number one princess.
