One day they went to the park and Rui came across Tsukasa wearing his school uniform, he was looking into space as if in deep thought.
"Tsukasa, what's wrong?" Rui asked him.
"I'm just thinking about my future." Tsukasa answered.
"Ooo~ Maybe i am your Future Tsukasa kun?" Rui flirted with Tsukasa.
"Y-You're not my type, or yeah." Tsukasa said, walking two steps away from Rui.
"Wanna have some fun with me?" Rui ask him again.
"No!" Tsukasa replied in a harsh tone of voice.
"Come on, I'll do everything you want~" Rui teased him again.
"Everything? Then, shut up." Tsukasa said, as Rui frowned.
"You don't act like the usual, 'kasa kun." Rui said.
"What did you mean by that?" Tsukasa asked seriously.
"Its okay if you don't wanna answer. But I think you might want to talk about it." Rui said while smiling at Tsukasa.
"No, i dont. Leave me alone." Tsukasa said.
"Fine, I understand." Rui said and walked away from Tsukasa, going to an Alleyway.
Just then Rui saw Ruri who is one of his female friend and Tsukasa's childhood friend. He was surprised to see her after a long time.
"Hey, Rui! Long time no see~" Ruri said happily.
"Hey there, Ruri. Nice to see you too." Rui replied.
"Same here, Rui." Ruri replied.
"and also, I just saw you and Tsukasa. Whats wrong?" Ruri asked Rui.
"Nothing really." Rui replied.
"Is something bothering Tsukasa?" Ruri asked him again.
"Not really... I guess." Rui answered.
"Really?" Ruri smiled.
"Im not sure, oh and look! He is coming near us," Rui's eyes widened up
"Hey there Ruri, long time no see! And Rui, sorry about earlier." Tsukasa apologized.
"its alright Tsukasaa~" Rui said, grinning.
"So.. anything new?" Ruri asked.
"Nope." Tsukasa replied.
"Ehehehe, but i should get going now, its getting late. Until we meet again!" Ruri said, leaving Tsukasa and Rui both alone in an alleyway.
"Oh, shes gone already." Tsukasa sighed.
"Well, atleast we can fix things up from earlier, right?" Rui smirked.
"Yeah." Tsukasa said, nodding.
"Good!" Rui happily smiled.

It was two weeks later, Rui and Tsukasa were having lunch in the cafeteria when Rui suddenly remembered something important.
"Umm, Tsukasa..." Rui said while scratching his head.
"Yes?" Tsukasa replied.
"Remember that thing we talked about before? Yeah, the thing where we will become a couple." Rui said excitedly.
"Oh.. that one childhood promise i would love you?-" Tsukasa turned red.
"Im just teasing, i'm pretty sure your still uncomfortable being in a relationship." Rui said.
"Y-Yeah. But i think its fine now." Tsukasa said.
"You're not joking right?" Rui asked.
"Of course not. Why would i joke about this?" Tsukasa kissed Rui on the cheeks.
"Haha, thank you. I feel so relieved." Rui said happily.
"Does this make us a... couple?,," Tsukasa asked Rui.
"Yeah, i think so." Rui said.
"Okay, good!" Tsukasa said while getting closer to Rui.
"Hm?" Rui gasped.
"Sorry for making you wait." Tsukasa said, kissing Rui on the lips.
