Yukino under Yukino's apartment.

When Su Yu returned home, he looked at the other pair of shoes in the hallway, and was slightly taken aback.

"Su Yu-kun, good evening." Yuihama Yui in pajamas appeared in front of Su Yu.

"Yui Yi, what are you..."

"Can't I come?" Yuihama Yui pursed his mouth.

"Of course I can come, but..." Su Yu looked at Yuihama Yui.

"Su Yu-kun, don't think of strange things!" Yuihama Yui's face blushed.

"Yui, I can't blame me, who made you so cute." Su Yu changed his shoes and came to Yuihama Yui.

"Do you say the same to other girls?" Yuihama Yui turned his head.

"Yes." Su Yu took it for granted.

"Stupid." Yuihama Yui puffed out a small face.

"You know the answer, but Yui has to ask me, he is a fool." Su Yu took her little hand.

"I... I also want to hear some other answers from you." Yuihama Yui said aggrievedly.

"Other answers?" Su Yu gently hugged Yuihama Yui and leaned to her ear.

Yuihama Yui blushed and lowered his head.

"Yui Yi is the cutest girl in my heart. She has a good figure and is very deceiving. I will listen to what I say." Su Yu whispered in her ear.

"I...I'm not good at deceiving." Yuihama Yui retorted quietly.

"In fact, Xiaoxue is Lily."

"Huh?" Yuihama Yui was taken aback.

"You lied to you, fool Yui." Su Yu smiled.

"Jun Su Yu, fool!" Yuihama Yui glared at Su Yu in shame.

"Kyui, don't have strange thoughts about Koyuki. If that happens, I will be very troubled." Su Yu smiled.

"I won't have strange thoughts about Koyuki!" Yuihama Yui gave Su Yu a white glance.

"By the way, where is Xiaoxue?" Su Yu questioned.

"Koyuki is in the bathroom..."

"Oh, I'll take a look." Su Yu released Yuihama Yui, ready to go to the bathroom.

Upon hearing this, Yuihama Yui quickly stood in front of Su Yu.

"What's wrong? Yui." Su Yu looked at Yuihama Yui knowingly.

"Su Yu-kun, Koyuki is in the bathroom, what are you going to do?" Yuihama Yui flushed.

"I want to go to the bathroom too. It just so happens that Xiaoxuna is in it now, so I can ask Xiaoxuna to help or something." Su Yu said seriously.

"If you are like this, Koyuki will be very troubled!" Yuihama Yui flushed.

"Koyuki will not be bothered. Before, when I went to take a bath, Koyuki asked me if I needed help. When I refused, Koyuki seemed very lost, so I planned to give her a surprise." Su Yu was very serious about lying, and he didn't even blink his eyes.

"That can't go either." Yuihama Yui was very shy, but still didn't give in.

"I'm Koyuki's fiance, why can't I go?" Su Yu smiled and looked at Yuihama Yui.

"Because...because..."

"Because Yui doesn't want me to go, right?"

Yuihama Yui heard this and looked at Su Yu, she did think so, but she didn't dare to say it.

"Stupid Yui, how could I do something like that in front of you, just trying to tease you." Su Yu stretched out his hand and patted Yuihama Yui's head.

"Really just teasing me?" Yuihama Yui was a little disbelief.

"Of course. By the way, Yui, do you want to join hands with me and play tricks on Koyuki?" Su Yu thought suddenly.

"To play tricks on Koyuna together?"

...

After half an hour.

Yukoshita Yukino walked out of the bathroom.

She was about to head to the living room when she heard strange noises coming from the room.

Xuexia Xuena approached the room, and when he listened carefully to the sound in the room, his face instantly turned red.

Yubihama Yui's voice was in the room. She seemed to be resisting Su Yu, but it sounded like a girl's shyness.

"Su Yu-kun, you can't do this, Koyuki will come out of the bathroom soon." Yuihama Yui reminded.

"It doesn't matter, when Xiaoxuna comes out, we can be three of us together." Su Yu smiled.

"Jun Su Yu, you...you are really bad."

"Don't you like me so bad?"

Xuexiaxuena listened outside the door, her face was a little hot, but she did not leave.

"Yui, did you prepare that thing?"

"That thing?"

"Stupid Yui, that's the thing..."

"That kind of thing, I...how could I prepare!"

"Then it's a little troublesome, in case, if something unexpected happens..."

"Jun Su Yu, fool..."

Yukino Yukino heard this and remembered the box.

Suddenly, the door of the room opened.

Xuexia Xuenao was stunned.

She did not expect that the door of the room would open at this time.

"Xiaoxuna, what are you doing standing outside? Come in." Su Yu stepped aside.

Yukoshita Yukino looked at the bulging quilt, Yuihama Yui had already got into the quilt.

"I...I won't bother..."

Su Yu didn't wait for her to finish speaking, stretched out her hand and pulled her into his arms.

Then, the door of the room closed.

Xuexiaxue Nai leaned against Su Yu's arms, her heart was full of tension and shyness.

After all, Yuihama Yui was also present.

"Xiaoxunai, is that okay?" Su Yu looked down at Xuexiaxunai in his arms.

Yukino Yukino knew what Su Yu was asking, and he glanced at Yuihama Yui's direction and hesitated.

"Yui Yi has promised and will accept everything from Koyuki." Su Yu saw her hesitation.

Xuexia Xuenai raised her head, looked at Su Yu, and hummed softly.

"Yuiyi, you can get up." Su Yu let go of Yukino, and said to Yuihama Yui.

Yuihama got out of the bed, dressed in Yukino Yukino's bunny costume.

Xuexia Xuenao was stunned for a few seconds.

"Xiaoyuki, I'm sorry, I changed into this outfit without your consent." Yuihama Yui apologized.

"No... it doesn't matter." Xuexiaxue Nao smiled reluctantly.

"Yui Yi, don't be so nervous, didn't Koyuki agree just now?" Su Yu smiled.

"Huh?" x2

"I just asked you, is it okay? It means to ask if you can let Yui wear your clothes. Isn't your answer yes?" Su Yu pretended to be puzzled.

"You...Is this what you asked?" Xuexia Xuena didn't react.

"How about it?" Su Yu blinked.

Xuexiaxuenai blushed, always feeling that Su Yu was teasing her and deliberately misunderstanding her.

Yuihama Yui couldn't bear to see Yukino's performance.

"Xiaoyuna, everything is actually Su Yu-jun's plan. The voice just now was Su Yu-jun asked me to say that, just to make Xiaoyuki misunderstand us and play tricks on it."

Yukino Yukoshita heard Yubihama Yui's words, the blush on her face disappeared, holding her small fist, she looked at Su Yu in shame.

"It's getting late, you guys rest early, and I sleep on the sofa." Su Yu smiled and ran away.
