Sulli couldn't concentrate on her work the whole day. Minho noticed she was acting weird as he came out of his office. "Sulli-shi is something wrong?" Sulli didn't hear him because the thoughts of Heechul coming are still roaming in her head."Sulli-shi!" Sulli got startled and realized it was Minho. "Oh Bian Minho-shi..."  Minho:"is something wrong? Sulli looks at him and says "ani nothing's wrong I just can't concentrate on my work" Minho nods and goes into the restroom. "Weird she was fine this morning." He said to himself.    -At lunch break-   Victoria:"Bwoh? Kim Heechul your first love?"  Amber:"Sulli what are you going to do?"  Sulli just pokes her food around with her fork and say "I don't know..." Victoria:"How about this just focus on your Cold Boss Araesoe! Since it's our dare and don't mind Heechul..he's history."  Sulli just sighs and stares somewhere else. Amber and Victoria look at each other and just sighs with her too. Minho was close by and heard them talking "Kim Heechul is her first love.." And then he remembered her saying she liked someone before when they went out to eat. A part of Minho was mad...but he didn't know why.    -Next day Heechuls arrival-   Sulli was getting nervous..after so many years did she really fail to forget him.    -flashback-   Sulli was about to enter Heechul's apartment when she saw a girl coming with Heechul down the hall.  Sulli:"Oppa...who is this?"  Heechul:"ahh this is my girlfriend Krystal."  Sulli:"Ne?...you girlfriend?" Krystal just looked at Sulli up and down.    Heechul:"what are you doing here Sulli?"  Sulli was going to confess to Heechul about her feelings because she thought he might have felt the same for her. But the least expected happened.  Sulli:"Ani-yah. Never mind I came to tell you something but I forgot it..ehhehe *on the verge of crying* I'll go now" and she ran off.    Krystal:"what's her problem? And how do you know her?"  Heechul:"ahh Sulli? She's a girl I know from school we went to highschool together. Don't worry I we're just good friends and she's like a dongseang to me"  Krystal"tsk...looked like she liked you I'm jealous. Oppa don't have any other girls around your house Araesoe?!?!?"  Heechul:"Araesoe. Uri Krystal knows how to get jealous too. Kekeke"    -flashback over-    Minho:"Sulli-shi get ready to greet Kim Heechul he will arrive in 10 minutes and tell the rest of the employees to also" Sulli:"okay I will Boss"  Minho:"hey...I told you to call me Minho"  Sulli:"oh...I'm sorry Minho-shi"  Minho knew why she was acting like that and he it was bothering him.    Heechul finally arrived. Everyone greeted him and saw Sulli stranding beside Minho Minho:" Hello *shakes Heechuls hands* I'm Minho the director here"  Heechul:*smiles*"I know and nice to meet you." He looks at the person next to Minho"Oh! Sulli is that you?"  Sulli:"Welcome Heechul-shi" and bowed to him.  Minho:"ah. This is Sulli my secretary"  Sulli couldn't look at Heechul in the eye. Heechul:"Sulli-ah why are you acting so formal just call me Oppa like you always used to."  Minho looked at him and cleared his throat "well wince we all greeted you already
