While Mr. Su Rui was getting close to Kaguya Shinomiya, Shirai Kuroko had already arranged Misaka Mikoto's accommodation and prepared some daily necessities for her, even giving her some clothes she had bought but never worn.
"Alright! This should be fine for now. Sister-sama has been busy all day, so go take a bath and rest early."
Shirai Kuroko nodded, satisfied with the results of her long efforts, then looked at Misaka Mikoto:
"Since that's the case, I'll go back and rest now. My room is right next to Sister-sama's. If you need me, you can knock on my door anytime~"
"Okay, Kuroko, I understand. Thank you for helping me."
Misaka Mikoto managed a faint smile to express her gratitude to her junior, but Shirai Kuroko just waved her hand: "Sister-sama, really, these are just trivial matters."
With that, Shirai Kuroko closed the door and left Misaka Mikoto's room.
Pretending as if nothing had happened, Shirai Kuroko entered her own bedroom, quickly leaned against the door, and locked it from the inside.
The girl's breathing gradually became rapid, and the calmness and composure she had displayed in front of Misaka Mikoto seemed to vanish in an instant.
Breathing heavily, Shirai Kuroko listened carefully to the movements outside, even taking out her phone and setting an alarm.
Five minutes. If Sister-sama didn't disturb her within five minutes, it meant she probably didn't need any help.
So, with the countdown set, Shirai Kuroko leaned against her door, passing the time by looking at her phone.
The five minutes, which usually seemed so short for her no matter what she was doing, now felt especially long. In those short five minutes, Shirai Kuroko checked the time on her phone multiple times, only to find that barely a minute, or even less than a minute, had passed.
'Time is passing so slowly. No, Kuroko, you need to learn patience, otherwise it won't be good if you're discovered.'
With this thought, Shirai Kuroko patiently waited for about five minutes. When the countdown alarm on her phone rang, she couldn't hold back and immediately activated her coordinate transfer ability, appearing outside of the critical area.
Then, Shirai Kuroko pressed herself against Misaka Mikoto's door, listening to the sounds inside through the door.
She seemed to faintly hear the sound of running water, which meant Sister-sama was currently taking a bath.
After confirming Misaka Mikoto's activity, Shirai Kuroko breathed a sigh of relief.
This meant that her Sister-sama wouldn't disturb her for a while. In that case, maybe after she finished her plan and returned to her room, Sister-sama wouldn't have visited her.
With this thought, Shirai Kuroko checked one last time, and after confirming that Misaka Mikoto was taking a bath, the red-haired twin-tailed girl tiptoed through the castle corridor, even using coordinate transfer to quietly approach her destination, which was Mr. Su Rui's room.
"Hehe, hehehehe~"
Arriving at Mr. Su Rui's door, Shirai Kuroko couldn't suppress the smile on her face as she imagined how surprised yet delighted Mr. Su Rui would look when she entered.
For this moment, she had even quickly changed into a black lace killer lingerie during those five minutes.
Although it took less than a minute to change, Shirai Kuroko was very confident in herself.
With this thought, she quickly arrived at Mr. Su Rui's door, listening carefully for any movement inside, but found nothing.
Then, Shirai Kuroko used her coordinate transfer ability and entered the room directly.
What was Mr. Su Rui doing now?
Shirai Kuroko's lips curved into a triumphant smile as she scanned the room, only noticing a small bulge under the covers on the soft bed, with someone seemingly moving inside.
'Hmph, hmph, could it be that Mr. Su Rui is alleviating his loneliness alone? How pathetic. Why didn't he just tell me, Kuroko? I would have laughed at him heartily, then helped him solve the problem.'
Shirai Kuroko's smile became even brighter. She used a coordinate transfer to appear directly above the bulge, then sat on it, triumphantly pressing down on the quilt and saying:
"Hmph, hmph, caught you, didn't I? What are you doing here alone? Didn't I, Kuroko, tell you that if you encounter a problem, you can come directly to me?"
The "Mr. Su Rui" in the covers tried to struggle, but Shirai Kuroko held down the quilt tightly, not allowing the person inside to come out, while she continued to speak arrogantly from outside.
"Mr. Su Rui, you must really want to get close to me, right? You try to please me in various ways but don't say it directly, instead making me watch you flirt with other women. How hateful. You must apologize to me properly before I satisfy you, you know~"
The "Mr. Su Rui" in the covers seemed to be angered. After adjusting a bit, a foot kicked out, sending Kuroko, who was sitting on the bed, flying.
Fortunately, she reacted quickly, swiftly using her ability to stand on the floor, while looking at the bed with dissatisfaction:
"Hey, I was just joking with you! Why are you so angry?"
Although she was annoyed with her own rashness, Kuroko still didn't let up verbally.
Then she saw that the person who emerged from the covers was Yotsuya Miko.
Yotsuya Miko, who came out of Mr. Su Rui's covers, was completely flushed. Her golden eyes stared intently at Shirai Kuroko, who was standing by the bed, breathing heavily, not knowing if it was because she had been muffled earlier.
Shirai Kuroko also fell into a dazed confusion, looking at the girl in front of her, swallowing, and after a long while, she asked: "You..."
"Mr. Su Rui went to accompany Kaguya Shinomiya."
Yotsuya Miko interrupted Shirai Kuroko's question, then the girl breathed heavily, looking at Shirai Kuroko standing in front of her:
"Mr. Su Rui is not lacking in girls around him, Miss Kuroko, this won't work for you."
"Then is it a good idea for you to sneak into Mr. Su Rui's room like this?"
Shirai Kuroko retorted impolitely, hands on her hips, to Yotsuya Miko.
"I... I couldn't help it. After all, Mr. Su Rui doesn't have time to accompany me right now, so I can only pass the time here."
Yotsuya Miko's cheeks were flushed. She glared at Shirai Kuroko for disturbing her, then instructed:
"Remember to lock the door."
After that, she burrowed back into Mr. Su Rui's covers.
If it were Misaka Mikoto, she might not have guessed what she was doing, but Shirai Kuroko's knowledge was quite extensive.
Yotsuya Miko was comforting herself with the scent in Mr. Su Rui's covers.
