"Woonie!Hurry up,let's go to the park~The others are waiting" Hakyeon smiles,running as fast as his small 7 years old body allows him

Grinning as well,taekwoon runs along wih hakyeon, "Sorry,i had to ask for my parent's permission"

"Its okay- oh!There they are!" Hakyeon yells excitedly,pointing to the group of 4 children who's sitting in a circle,probably trying to decide what to play for today

Taekwoon nods,sprinting to them and hugging the one that's closest to his reach,jaehwan.Jaehwan giggles,hugging taekwoon as well "Oh!!You're here finally~"

Taekwoon smiles softly,releasing the 7 years old boy before turning to looks at the rest of the group "What should we play today?"

"Nothing that'd get our clothes too dirty,please" hongbin whines, "My mother scolded me last week because my clothes got dirty"

"Should we play tags,then?" Sanghyuk suggest,looking around at his friends

"Sure,that'd do!"

After they finally finished playing around and got tired,they prepared to go back home but taekwoon suddenly calls for them,fidgeting with his fingers a little

"What's wrong,woonie?" Wonshik asks,concerned 

"Mother and father told me that we're going to have to move away to some other city because mother got a job there" taekwoon replies almost a little too fastly,his eyes glassy

Silence envelopes the group,everyone not knowing what to say or do

"I- i thought we promised to stay together forever?" Sanghyuk asks,his voice shaking from the tears he's holding back

Taekwoon shakes his head,small drops of tears already spilling from his eyes, "i know,but I couldn't do anything"

"Why didn't you tell us sooner?" Jaehwan asks,lips shaking

"I didn't want to ruin the mood" taekwoon's head is bowed to the ground,trying to hide the tears falling from his eyes "im sorry"

There's a silence again before it was broken by shaky sobs that comes from hakyeon who immediately runs and pulls taekwoon into a hug "you better not forget us"

Seeing them,hongbin quickly follows along and joins the hug,sobbing hard

The other three joins the hug too,all of them basically just a sobbing mess by now

"Im sorry,im sorry"

On the day taekwoon moves,they hugged again,promising each other that no matter what happens,he wouldn't ever forgets them and that he would send letters everyday.They stays together as long as they can until taekwoon's mother comes,smiling gently,telling him that it's time to go.

They can see taekwoon's eyes being glassy again but he seems to be holding it in,trying his hard to smile "Goodbye!Make sure to reply my letters everyday!"

Taekwoon holds his promise to write to them everyday but it keeps decreasing when they grows older but it's better than anything so they didn't complain

They're okay with any sorts of contacts as long as they can still interact with the gentle soft spoken boy.

Until the letters abruptly stops coming.

They waits and waits,telling each other that taekwoon is probably busy with homeworks and that they should wait no matther what happens because taekwoon had promised them that he wont forget.

He had promised.

But the letters never comes anymore.
