After the drama is finished Lin Wen came to Lan Yue and remembered him his promise that he will accompany her the festival to which he also agreed.
Lin Wen: "Yue'er you have promised me to accompany in the festival, do you remember ?"
Lan Yue: "Yes Wen I remember and I will also fulfill my promise with you."
Lin Wen: "Really. Thank you so much Yue'er. So let's go right now."
Lan Yue: "Okay."
After that they went to their separate changing rooms. There they changed their costumes and got rid of their make up.
Then they both came out of their respective rooms and met outside of the room and then they both went from that place to enjoy the festival.
When both Lan Yue and Lin Wen went out of that place A'Xin saw them going out of that place. She also saw that Lin Wen is holding Lan Yue's hand in her hand.
This thing made more sad and she just got overwhelmed by her own emotions about which she also don't know.
