"Are you okay?" Wakasa asked and come to her. "Can you help me?" She asked, and Wakasa eyebrows furrowed. "What is it about?" He asked. "I need a place to stay tonight. Can you help me with that?" She asked. He confused with what she just said. What she said with what he asked is really not relatable at all.

"I know I'm completely stranger. But, please. I will make sure to pay back your kindness if you help me." She pleaded. Wakasa never think that it will become a long story.

All he could think that time is she may be just a little girl who run away from home because her parent give her a lesson. She just afraid to come back tonight, and tomorrow she'll leave.

He said and pointing the couch in the corner of the room. "Thank you so much Sir.." She said.

"Wakasa Imaushi. Call me Wakasa." He said. She nodded. "What's your name?" He asked. She gulped, "Ke-Sierra! My name is Sierra." She said. "A rare name. Like a foreign." He commented while rummaging a cabinet near there. She just remind silent and sit on the couch.

Wakasa silently observe her through the tip of his eyes. She's not just had bruised and wounds. She's beaten up. Her cloth even ripped a little here and there. "You can look at me directly Wakasa-kun. I know you had a lot of question for me." She said make Wakasa a little surprised that she know he observed her. 

"So, what's your story?" He said while throw the first aid kit to the table signing that she can use that. She opened the first aid kit, "I just lost a fight, and flee." She said while patch her bruised and wound skillfully. She didn't even hissed. "What about you Wakasa-kun?" She asked back. "Same here." He said. 

"Adult people usually didn't involved to fight." She said. "Yeah. But I'm not usual." He answered. "A good friend of mine is a girl around your age. You can use her cloth, and here some blanket for you. Good night." He said  give her a cloth and blanket before he entered the  door that connecting his boxing gym to his house. 

In the morning Wakasa is coming to his boxing gym to check on Sierra and of course running his gym. When he entered the gym he surprised to find she clean up everything. All of it looks so clean and shining. Sierra smile brightly, "Good morning Wakasa-kun!" She greet him. "You did all of this?" He asked to her and she nodded. "At least I did this right? You've been so kind to me." She said.

Wakasa nodded and opened his boxing gym for customers. He didn't mind at all, since he's kinda lazy to clean things up. "Thank you then." He replied. Surprisingly the first customer come in at that time, "Woah! You just clean up the whole gym? " He said in excitement, then he saw Sierra. She smile to the customers. "Oh.. It's looks like you hiring someone.. It looks really clean and shining, she did it well huh?" He said.

Sierra cleared her throat, make Wakasa and Benkei look at her. "Who is her?" Benkei asked. "Thank you once again Wakasa-kun. See you." She said bowing to him, and walk out from the gym. Wakasa eyes is glued to her until she closed the door. "Okay who is she Waka? You seem interested to her." Benkei asked again and Wakasa look at him. "Just a random girl." He replied.
