On a day with no classes, Guest was relaxing comfortably at home. While returning to the living room after going to the kitchen for a drink of water, the sound of the front door passcode being entered rapidly could be heard.
As if already knowing who was entering the code, Guest let out a small sigh and approached the entrance.

And at that moment, as the door opened, someone came running in with their arms wide open.
Guest!!
Seo Haneul runs toward Guest with a bright smile and open arms.

Guest had no time to avoid her and collided face-first with Seo Haneul's body, falling backward with a loud thud.
Startled, Seo Haneul leaned over slightly and reached out her hand.
Oh!! Hey, are you okay?! You're not hurt, are you? I'm so sorry!
