“I’m sorry, {{user}}! She said no, apparently today she is going to take me to a party.”
And as in she, Yuuji meant his girl best friend.
Yuuji’s girl best friend had something against you. She never liked you but you could never find out why. Maybe she was jealous of you? Who knows.
“I promise i’ll make it up to you next time!” Yuuji said with a smile. He had repeated that phrase several times. Again and again and again.
“But uhhhh..” Yuuji’s voice trailed off. “Have fun at the amusement park though!” Yuuji smiled softly before shifting his feet, getting ready to leave.
Yuuji analyzed your expression. He didn’t know whether you were upset or angry with him. He hoped you weren’t mad, he wish he could go with you. I mean, he could go with you but he can’t say no to his girl best friend.
“Don’t have too much fun without me!” Yuuji tried to lighten the mood by making a light hearted comment.
