While driving hes way home,  Sukkie can’t stop thinking of Yoona, so he stops the car and was about to open the gift she gave him, but he was stop by a call from hes mom.

Mrs. Jang: Son, are you on you’re way home? Drive safely.

JGS: Im there in a minute mom,.

Then he hangs up and continue driving, when he got home, her mom is waiting for him,

JGS: Omma, did you wait for me?

Mrs. Jang: yes, im just worried, what took you so long.

JGS: ah, Soo is not yet there when we arrive, omma, what wrong with your eyes?did you cry?are you sick?

Mrs. Jang: ah, nothing, there’s just something that got in my eye, we better rest now.

JGS: Ok, im going to my room.

When Sukkie got in his room, he seat on the edge of hes bed and slowly open Yoona’s gift to him, he smiles when he saw the Blue leather laced watch, but then his heart starts to pound when he saw a letter with it,

Yoona

Sukkie’s heart is breaking reading Yoona’s letter that he just cry on his knees uttering her name while hugging the letter. “Yoona...Yoona ...Yoona” He tries to dial her number but its not attended, he tries to call Soo but its not attended too, on that moment he can’t do anything but to think,  and to hope that it will be ok.

Mrs. Jang can’t stop her tears too, she just want to hug her son and comfort him, but she know’s he needs a time of his own. When she got back on her room, she just hug the cardigan that Yoona gave her, reading again her letter makes her heart to break;

Omma,

I gave you this Cardigan because it represents what you are to me, im really thankful to have known you, omma you’ve warm my cold heart, i’ve never felt the love of a mom, but you gave it to me, you treat me like your own daughter, and ill be forever thankful for that, Omma i dont know how can I say this to you, I know how it will hurt you, but...Omma im breaking up with Sukkie, I love him so much thats why im doing this, I know how it will hurt him but this is the only thing I could do, Omma I know you’ll get mad at me, but omma im hoping to hug you again, i hope you can forgive me for hurting your son, i didint mean it, omma minaeyo,..omma sarangheyo...please take care of Sukkie for me, I love him with all my heart.

Mrs. Jang can help her self but to cry, she wants to get mad at Yoona, but she doent know why she feels more sad for her, she doesnt know whats her reason for breaking up with her son, but she trust her, she knows that someday she’ll be back and they’ll be happy together again.

On the other side, Yoona and Sooyoung go directly to the SM office to surrender their phones and gadgets, Soo knew that it will be hard for Yoona to stay at the dorm on her condition so she ask the presidents permission to stay at their home for that night. When they arrive, Yoona immediately lie on the bed, she looks so weak and pale. Sooyoung was worried sick for her, so she ask her if she want to eat, but she just said she wants to sleep. She leave her for awhile to get her a glass of warm milk,

Soo: Yoong...drink this first, it will help you to sleep,.. (then she help her get up)

Yoona: Thanks onnie, thank you for always being there for me

Lying on the her arms, Sooyoung hug Yoona to comfort her, she’s patting her back gently advicing her to be strong. Even if it breaks her heart seeing Yoona in that condition, she needs to be strong for her, and share her heartaches.
