4 years later...
It's in the morning. There's a bird chirping outside the house ( idk why but i laugh at this tsk hahaha ) and the sound of alarm waking her up. sana opens her eyes and starts stretching her body. She looked beside her and smiled. She caresses his cheek and kisses it. he stirred in his sleep and whimpered making sana giggle. she start pinch his cheek cutely making him whine. 
" mommy. "
" hehehe. morning baby boy. "
" morning mommy "
It was a sana child, she named it satchew. ( why? because satchew is satchew. haha ) the 3 year old kid Satchew continued to sleep while hugging his dog plus squirrel plushie. He hugged tightly making sana shook her head. She decided to make breakfast for both of them. 
it's been 4 years. there's so many things that have changed. sana never been in a relationship anymore. it only hurt her and she will never face the same thing again. She doesn't trust men anymore. but not that she hates them or she will not fall in love again, maybe one day she will. about her ex boyfriend, yeah she thought that he is her ex boyfriend although they never say break up. She hears that he already got married to the girl he proposed to. Of course it hurt sana so much. it hurts her and she hates him, until now. they never contact anymore and sana told herself not to care about him anymore and just focus with her child. There's one time Satchew asks where's his father, sana smiles sadly and tells him that his father is dead from an accident. It makes him sad because he was born without a dad but he loves his mom and promise will take care of her when he grows up. He says excitedly, making Sana want to cry. He even says that if there's a man who wants to take her, they should meet Satchew first. It makes Sana laugh. satchew face was serious when he talked. sana hugged him and nodded. 
She finished making breakfast and walked upstairs to wake her child. She got inside and saw her child still sleeping. she patted his butt. 
" wake up handsome boy. breakfast is ready. you want a new toy and eat ice cream today right? "
In a couple of seconds, he gets up and runs. being a clumsy he is, he trip and fall on the floor. he rub his butt but he get up fast and not looking at his mom. he give a sign ✌ while get into the bathroom. he shouting..
" I will go downster mommy! wait for me! I brush my teeth first! "
Sana laughs at how excited he is. She told him that today they will be going out and having some fun since she's not working today. Sana prepared his cloth to wear later and put it on the bed. satchew then walk out from the bathroom and grin. They both then walk downstairs and start taking breakfast. 
Meanwhile, Tzuyu just arrived at his destination, canada. he got out of the airplane and waited for his people to pick him up. 10 minutes later, he got inside his car and the driver drove to his house. While waiting to arrive at his house, he just played with his phone. He opened his gallery on the phone and saw there are so many pictures of her with him together taking a picture. He smiled sadly and sigh. 
I miss you sana. I wonder where you are right now? i'm sorry. 
without him knowing, sana is living in canada.
