The Door of My Bathroom Leads to the Comic World!

Utaha gritted her teeth, faint veins visible on her forehead. It was clear she had already clashed with this student a few days ago, but despite her sharp tongue, she hadn't managed to gain the upper hand. After all, there were five of them. No matter how eloquent she was, she couldn't handle them all at once.

"Where's Ichika? Why isn't she here yet?" Utaha took a deep breath and asked coldly.

Sui glanced at her in surprise. Just a moment ago, this girl hadn't denied being called her boyfriend. Perhaps she was too angry to notice?

"Ichika's still sleeping. Let's not wake her," Yotsuba quickly replied.

"What nonsense! Sleeping in the middle of the afternoon? Does she even take me, her tutor, seriously?" Utaha stood up in frustration. Without hesitation, she grabbed Sui's arm and headed upstairs. Stopping in front of a door, she turned to Yotsuba. "Is this her room?"

"Yes..." Yotsuba hesitated for a moment in front of the door.

"What's the holdup? Hurry up and open it," Utaha urged, her patience clearly running thin.

"Uh, sensei... and sensei's boyfriend, don't be too shocked," Yotsuba said with an apologetic smile as she opened the door.

The room was dim with the curtains drawn, but when Yotsuba flicked on the light, a horrifying scene unfolded before Sui's eyes.

"Is this really a girl's room?" Sui muttered, his mouth twitching.

The floor was littered with clothes, makeup boxes, shopping bags, and magazines, leaving almost no space to walk.

"This is a disaster! How outrageous!" Utaha folded her arms, her voice icy with disapproval.

Sui, however, glanced at her, speechless. 'Your room isn't exactly spotless either,' he thought.

"Aren't you the one who leaves your stockings everywhere?" he whispered under his breath.

Utaha blushed furiously, her foot stomping down hard on Sui's in embarrassment and anger.

"Oh, so sensei's got a messy side too. I never would've guessed. You sure have the nerve to act so perfect in front of us," Nino remarked nonchalantly, casting a dismissive glance their way.

Utaha was so angry she could practically hear her teeth grinding. She kept stomping on Sui's foot, as if punishing him for exposing her.

"Don't poke around other people's rooms like you're exploring some uncharted territory," a lazy voice said from beneath the bed covers.

The blanket shifted, and a girl with short pink-gray hair sat up, yawning. She looked at the pair in front of her with half-lidded eyes, still wrapped in the quilt.

Sui took one look at her and confirmed his suspicions—she was definitely one of the quintuplets.

Her light pink-gray hair was tousled, and she had earrings in both ears. Nestled in the quilt, she revealed a pair of smooth, white feet as she shifted.

"Oh, it's Kasumigaoka-sensei. Are you here to tutor us again? Hm? And who's this strange man?" Ichika's eyes landed on Sui, her curiosity evident.

"He's sensei's boyfriend," Yotsuba teased with a giggle.

"My, my, I didn't expect our strict and serious teacher to have a romantic side," Ichika laughed, clearly amused.

Utaha's face turned beet red as she ground her teeth in frustration. "He's not my boyfriend! We're just... friends! Now, get up already!" she demanded, storming over and tugging at the blanket.

"No, no!" Ichika yelped, but Utaha misunderstood, thinking she was just trying to stay in bed, and forcefully pulled the quilt off.

Suddenly, shocked gasps filled the room as everyone froze. Beneath the quilt lay Ichika's bare, snow-white body.

"W-What are you doing sleeping like that?" Utaha stammered, her face flushed crimson.

"I tried to tell you!" Ichika yelped, quickly pulling the covers back up, her ears burning red with embarrassment. It was bad enough that her sisters had seen, but now their tutor's supposed boyfriend had gotten an eyeful too. It was the first time a boy had seen her body.

"Uh, sorry... we'll wait outside," Utaha muttered, feeling a tinge of guilt. But when she turned to leave, she caught Sui still staring at Ichika's exposed skin. Furious, she grabbed his ear and yanked him out of the room like an angry wife scolding her husband.

"Wow, they really do act like a couple," Yotsuba couldn't help but chuckle.

Back in the living room, after a few moments, Ichika came out, fully dressed, her face still a little red. She sat next to Yotsuba, sneaking glances at Sui.

Sui, still agitated, cleared his throat as he inadvertently glanced at her chest. He had gotten a clear view earlier, and Ichika's figure was certainly curvier than Utaha's.

Suddenly, a sharp pain shot through his waist. Utaha had pinched him hard, her face calm, but her irritation evident.

"Alright, let's get started with the lesson," Utaha announced, crossing her legs and composing herself.

"Yes, let's begin!" Yotsuba cheered, eagerly raising her hand.

However, the other four girls seemed far less enthusiastic. Nino was fiddling with her phone, Miku was lost in her own world, and Ichika had her head resting on Yotsuba's lap, yawning as if she was about to drift off to sleep again.

Utaha took a deep breath, reminding herself of the steep tuition fees at Todai University and the extra high tutoring pay she was getting for this job. Otherwise, she might have already walked out the door.

"Do you all plan to be this lazy your whole lives? Are you just hoping a man will take care of you forever?" she scolded through gritted teeth.

As one of Toyogasaki Academy's top students and a successful light novel author at such a young age, Utaha couldn't stand the sight of rich girls who lacked ambition.

But the quintuplets were not easy to deal with.

Nino, calmly filing her nails with beautifully painted fingers, looked up and said with a hint of sarcasm, "Even if we're not good at studying, even if we're not smart, at least we're not hypocrites like you. My dad says you're the top student at a private school, always so perfect. But I didn't expect that even the 'perfect' Kasumigaoka-sensei would bring her boyfriend to a tutoring session. How scandalous."
