Mina comes back from Japan after a week. Her father's surgery went well. She lands in Korea at 9:30 PM. Right after landing she tries to contact Momo. 
Beep Beep....  No answer. 
Mina looks really worried. Why shouldn't she ? She only managed to contact Momo once while staying in Japan. She isn't sure why. Was Momo intentionally avoiding her, Is she still mad ? Or is there something wrong ? Mina gets into her car. She thought for a second she will visit Momo right now, but gives up since it is late. She tries once again but no luck.

It was Momo's mom's birthday 3 days ago. Last time momo told Mina to comeback fast so that they can celebrate it together, but Mina couldn't make it and had to ask Chaeyoung to give her mom a gift, it was a rabbit.
Is that has something to do with this ? "Nah I'm overthinking again." Mina says to herself. She tries to sleep while trying to calm herslef saying I'll visit her tomorrow. 

The next morning Mina sets out to visit Momo. She finds Momo in their yard. She is playing with the rabbit. Mina sighs and feels a bit releaved. She approaches Momo.
But.....
"Who are you?" Momo shouts. Mina gets a bit flustered by the response. 
"Why are you joking, Momo? I missed you for a whole week. You didn't even contact me. What happened? Are you mad at me?" Mina asks being worried but Momo starts screaming all of a sudden.
Momo's mom comes out and takes her inside asap. Mina is still baffled. What just happened....
