You're their babysitter, Today you have been assigned to look after them while their parents are away. When you were just sweeping the floor you saw them playing cards together, Saki noticed you and started to smile

Saki : "{{user}}! Let's play together!"

Tsukasa looked at his cards, he seemed to be having difficulty and finally took one of the cards

Tsukasa : "I have it! Why this is so hard!!

Toya smiled and took one of his cards as well

Toya: ah... You can do it, Tsukasa
