Chapter 151 – Tione’s betrayal. +18

*Ais's POV*

"Ais, how long has it been since they left?"

"I think about five minutes?"

"What do you think he wanted to talk about with Tione? Did something happen between them?"

"I don't recall anything happening between them. I've never seen them talk except when we're all together."

It was strange. Tione suddenly started acting oddly, like she was "out of touch" with reality. On top of that, Luan abruptly dragged her away, holding her hand.

I couldn't tell if he was holding her hand in an affectionate way or not.

I'm feeling a bit uneasy…

"Tiona, I'm going after them."

"They said it was a private conversation. Are you sure you want to go?"

"Didn't you replace it strange? I feel like something isn't right."

"Wait, do you think Luan is doing something to Tione? Don't you trust him?"

"..."

She was right. I like Luan. I'm falling for him more and more for some reason. So why am I doubting him like this? If I want him by my side in the future, I need to trust him.

But still… I feel like I should look for them.

So, I headed in the same direction they went.

"Ais, wait," Tiona called after me and decided to follow.

Mmm~~

Mmm~~

After walking a few meters, we heard some soft, muffled moans. They grew louder as we approached one of the dungeon rooms.

...

The moans became more intense as my heart raced faster.

"Ais..." Tiona grabbed my hand. "I don't think this is a good idea."

"Why? What's going on?"

"It's better if you don't see. You like him, don't you? It's better to ignore this and go back."

Mmmmmm~~

MmmMMm~~

MMMMmm~~

"Tell me, Tiona. What are they doing in there?" I asked her, already suspecting the answer.

"I don't know."

"They're doing that, aren't they? Since when have they had this kind of relationship? Did you know about this and not tell me?" I said coldly to Tiona, but she denied knowing anything.

She seemed sincere.

But maybe I'm overthinking. Perhaps nothing is happening.

I decided to move forward—I wanted to see with my eyes. However, Tiona grabbed my hand to stop me. "Ais, if they're really doing that, you don't need to see it. I know you like him, but it's better to forget about him."

"How can I forget him when he's the first man I've ever been interested in? And why with my friend?"

"I never thought I'd hear you say something like this. Are you really Ais? Has this guy changed you so much?"

"Tiona… I think my heart is breaking. Isn't this what happens when the person you like betrays you? Especially with a friend."

I pulled my hand and moved forward. I wanted to see with my eyes, even if it hurt more.

"Ais!"

"..."

I ignored Tiona's voice and headed toward the increasingly intense moans.

And then I saw it.

Luan was without his pants, and Tione was practically naked. He was holding her in his arms, pressing her against the wall as he… penetrated her.

I froze, staring at Luan's back, which hadn't noticed me yet.

Then he turned around, startled.

His eyes met mine, and tears welled up in my eyes.

I changed so much because of you. Why did you have to betray me?

"Luan?" I heard Tione's voice calling for him. Moments later, she saw me, too. "Ais?" She looked as shocked as Luan.

"Tione! What do you think you're doing?! Are you insane?!" Tiona arrived, yelling.

"Tiona?!" Tione quickly pushed Luan away and began dressing herself.

"Do you have any idea what you're doing? And Luan, since when have you had this kind of relationship with my sister?!"

"..."

Luan said nothing and remained silent.

"Luan." I called his name, and he looked at me. Then, his lips curved into a smile.

"I'm sorry," he said.

Sorry? Is he apologizing to me?

But before I could say anything else, my vision went completely white.

####

*Luan's POV*

I was moving my hips, but I felt some presences approaching behind us. I was too distracted fucking Tione, and by the time I noticed, it was too late. When I looked back, I saw Ais standing there, watching us.

She had no expression. She showed no emotion.

"Ais?"

"Tione! What do you think you're doing?! Are you insane?!"

Then Tiona showed up as well. Tione pushed me away and quickly started putting her clothes back on. I watched everything calmly because I knew I could fix this. There was nothing to fear.

"Do you have any idea what you're doing? And Luan, since when have you had this kind of relationship with my sister?!" Tiona asked angrily.

"Luan…" Ais finally said something.

I looked at her and smiled. "I'm sorry."

I wasn't apologizing for having sex with Tione—I was apologizing for what I was about to do.

"Reset," I said.

After that, my vision turned completely white.

How much time had passed since I brought Tione to this place? Had more than ten minutes gone by?

Then, my vision returned to normal.

I was beside Tione, my shoulder touching hers. I hadn't yet used the skill [Sexual Attraction].

I had gone back to the right moment.

I looked at Ais and Tiona, who tilted their heads in confusion.

"Did something happen?" Tiona asked. "You seem a bit nervous."

"Nothing happened, don't worry."

I felt a bit nervous when I used the skill. I didn't know how much time had passed.

I'll complete the mission another time.
