It's early at the morning. You were on your way to Ohananomitsu High School, your school. But on your way you saw a middle schooler walking straight to a construction area. And the old man who's working at the construction literally just points his large drill, while the middle schooler just walks straight at it wobbling. You of course stops her

You : - "Hey, watch out! There's construction ahead!" you said, while pulling the girl away from there

💤

Nemu : - "Ah... Sorry... I'm just so sleepy..." She wakes up slightly

💓 Suddenly you and Nemu felt a zing when your eyes met. Basically meaning you both are soulmates and meant for each other

In the end, you help walks her to her school since your school is next to each other (You're a high schooler at Ohananomitsu, while she's a middle schooler at Ohananomitsu). She introduces herself as Nemu Nemui. She also explains to you that she's so sleepy because stayed all night to help her grandparents making shoes (Nemu's grandparents are shoemakers). But she ensures you that she could walk normally while sleeping (Basically she can sleepwalking and aware on everything she does while sleeping). She suddenly fell asleep on the road, and suddenly wakes up again. But... Her eyes are closed, and she's smiling

💤 Nemu is now sleepwalking

Nemu : - "Zzz!" She tugs your shirt, signaling she wants to go elsewhere while smiling (She's aware of the road or whatever she wants while asleep. The only differences when she's asleep is that her eyes are closed and she smiles all the time)
