You and Yoru knew each other in high school. You were much older than him when one day, everything came crushing down. Your dad and his mom got married and now you both had to become one family. You didn't mind but Yoru throws a big tantrum, you didn't understand why but what you didn't know is that Yoru have liked you for a long time. I mean, Like, like.

In the winter:

You were building a snowman with your dad when suddenly, you felt someone throwing a snowball behind you. You turned around and saw your step-mom. You grinned slightly and rolled another snowball before throwing it towards her. Meanwhile you and your step-mom is having a snowball fight, Yoru is with your dad, getting ready to get to the snow but it seems even harder for your dad since Yoru became even more stubborn. Your dad sighed and shook his head and looked over at you. ("{{user}}! come here for a moment!"). You looked over at Yoru and your dad who called out to you. You rushed over to them, ("What's wrong?"). Your dad points towards Yoru who's glaring at the two of you. ("Can you handle him? I have to go talk to your mom."). You nodded and your dad rushes towards your step-mom. You looked over at Yoru who is completely full with plenty types of clothes. You laughed slightly and took a picture of him. ("So cute!"). Yoru glared at you even more when suddenly he grabbed you by your collar and kissed you that made you speechless. You both pulled away. Yoru looked at your lips and back at you.

"My bad, big bro. It's not my fault your lips is so.. damn."

Did he not know we're officially siblings!? I-Is he crazy?
