I finished it!
Netherlands' POV
So far the conversation was going well. Belgium and Netherlands had begun to subtly flirt with Seychelles, watching her carefully to see her reaction to it all. Netherlands had noted that whenever he flirted with her she would act strange and move a little bit away from him. He also noted that she seemed to not be so bothered about Belgium flirting with her. Whenever his sister would say something flirtatious to her she would giggle nervously, a slight blush appearing on her face. Seychelles would also look away, he noticed, avoiding eye contact with Belgium. It was painfully obvious how Seychelles felt about Belgium now, and it was irritating him. He just really wanted to get to the point and ask her, yet at the same time, it could mess everything up. It was a risk he had to take, he decided, knowing that it was all for the sake of his sister.
"Seychelles?" he asked, interrupting her small conversation with Belgium.
"Yes?" she asked him, turning to face him.
"You have to swear you will answer this question honestly," he said to her, giving up with his original plan of being so subtle about it.
"Of course," she said, curious as to what he was going to ask her.
"Do you have a crush on my sister?"
Her expression changed at those few words. She no longer looked confused but shocked. Slowly a dusty pink blush spread across her face and she turned away, looking at her feet. Netherlands gave her a moment. He didn't want to push her to answer too soon. After a few minutes had passed, and as Netherlands was getting impatient, she finally spoke up.
"Yes," she said truthfully, her eyes still fixed to the sand beneath their feet.
Netherlands smiled. Belgium looked at him and he nodded, letting her know that she should confess too.
"Hey Seychelles. You shouldn't be embarrassed. Honestly... I like you too" Belgium told her, finally getting it off of her chest.
Seychelles looked at her in disbelief. Did she hear that right? Was this a dream? Was she even being serious?
"Listen, if you want to be my girlfriend then it's okay. I like you too. The only thing is the age difference. We will have to keep it a secret just now until you are old enough that it isn't strange. What do you say?" Belgium asked her, a warm smile on her face as she held out her hand toward the younger nation.
Seychelles didn't say anything. She didn't have to. A bright smile formed on her face and she took Belgium's hand. They entwined their fingers and Belgium kissed her forehead. Netherlands smiled again. He was glad that his sister was happy now, happy with her new found love. Now all he had to do, was to keep the secret safe, for the sake of the couple.
