I spent five days with an undead

When she comes out of her room in the morning, she finds breakfast already lying on the table.

The immortal is hiding somewhere. She can't pinpoint where.

With a deep scowl on her face, she finishes the food. Then she goes to take a bath, hoping that the immortal isn't shameless enough to peek while she's bathing.

Wakana gets ready for work. She can clearly sense his emotions. But she can't see him in the room. He's letting her know that he's here, but he's scared to show himself because of what happened last night.

She won't give in. Wakana pretends that she's not feeling anything and steps out of the apartment. After locking the door, she strides out of the corridor. His presence is right behind her.

Who is a ghost here? This creepy immortal is nothing less than a ghost.

There's no reply though. 

In the taxi, Wakana gets a call from her sister. "Elder Sister, you are home?"
