Singapore's name will be Jing yi, to give you context in the past Malaysia and Singapore created a federation with Singapore being a state but due to different ideologies they separated

"Do you think we can be together forever?"  "Of course lah!" So many memories plagued Malaysia's mind
"I'm so sorry sayang......"

Rewind
1965

"It seems we cannot reach an agreement no matter what we do it won't stop, and now I only have one option left at his point..." Malaysia said solemnly "please don't sayang please.. I'm begging you" Singapore pleaded to Malaysia but continued "and that is to divorce you" malaysia told Singapore looking at him straight in his eyes, as he looked at her he saw how her golden eyes were glazed over with unfallen tears that held heartbreak, her lips turned into a frown trembling at this side, "so-" Alysha slowly grabbed her ring sliding it off but felt a strong grip on her shoulders "tch! Just stop it! Stop!" Jing yi shouted at Alysha, his face had tears streaming down his face, his eyes held sadness and heartbreak and Malaysia felt like she hear his heart being broken.
"After all we've been through you're just going to call quits?! How could you say that so easily!? Do you not love me? Am I not enough!?" By now he was sobbing his face scrunched up, Malaysia's body was shanking as her tears finally let out she put her face into her hands weeping inside. She felt a hand bringing her face up wiping her tears. "I can't believe you Malaysia, did you really forget our promise?"
 
   

When they were children

"Jing yi! I was playing with belang and look what I have!" Malaya shouted to the boy resting under a coconut tree "why are you so filthy lo?" Temasak asked Malaya, he could see a vein on Malaya's head "I BROUGHT YOU BACK A DURIAN AND THIS IS WHAT YOU SAY TO ME?!" Malaya furiously asked Jing yi, she just sighed heavily "sometimes I wonder why I even bother with you" she said in exasperation, Jing yi just looked blankly "simple you love me" he said in a Kiasu way

10 minutes later~

They were now eating the durian that Alysha brought for them minding there own business until Jing yi spoke up "do you think we can be together forever?" He asked looking into the sky "of course lah!" Malaya answered cheerfully

Back to the Present
Malaysia looked at Singapore with a small smile, pulling on tie to give him one last kiss, this surprised Singapore but it wasn't unwelcome he gently held Malaysia's waist, malaysia pulled away from Singapore one of her hands reaching into her bag while the other holding his hand, she pulled out what looked like a scrapbook "here to remember when we were a couple" she handed over to him, she gave him one last tearful smile "goodbye sayang I'll always love you" she bid a goodbye leaving Singapore alone

Back to the actual present
She was so deep in thoughts that she didn't noticed that was about to bump into someone, "hey watch I!-" she cut herself off when she saw a red pinyin shirt and a man wearing glasses "Singapore?"

Hehe I'm leaving you like this
