"Ugh…"

Kael pinched his forehead and looked away from the books as he started to feel a headache from staring at so many words.

He finished reading all the books, learned something new, and also kept trying to create the rubber bullet.

While he wasn't successful just yet, he was feeling that he'd made some progress because he could imagine the rubber bullet better inside his mind.

"I need a drink."

Kael left his room and went to a kitchen wing that was close to the rooms and poured himself a glass of water.

It was from the water taken from the well in the town, and when the water touched his tongue, it tasted strangely refreshing.

"Cough! Cough!"

At that moment, he heard some coughing and saw that there was a person sitting by a table, right beside the open window.

It was Jeff, coughing against his fist, and he really didn't look good.

"Is everything alright?"

Kael also poured him a drink, gave him the cup of water, and sat across from him.

"T-Thanks…"

Jeff, with a trembling hand, drank to get rid of the cough, but it didn't seem to work, as as soon as he stopped drinking, he coughed a few more times.

He then noticed the Black Revolver in Kael's hand, playfully put his arms up in the air, and said.

"H-have you come to kill me?"

"You're looking pale. You should lie down and rest."

Kael said with a chuckle and lowered the Black Revolver in his hand to make sure of the gun safety.

It felt strange seeing him like that, as just earlier in the day during the dinner, he seemed completely fine.

In just a few hours, he looked like he was about to pass out and die!

"I-I probably should… Shit, I don't know what happened to me. I was feeling good just a moment ago, and then this…

"Maybe I got some disease from those fucking mines. Who knows what kind of toxic chemicals are down there…"

Jeff said with a pained gaze.

"Did you start to feel worse before or after you had sex with Teacher Angelica?"

Kael asked.

"…You saw, huh?"

Jeff chuckled weakly, coughed against his fist, and then lowered his head before saying.

"Immediately after… It was as if someone snapped their fingers, and I was hit with a ton of bricks."

"How long have you been in that kind of relationship with her?"

Kael asked.

"Uh… like two weeks, I think."

Jeff replied, drank some more water, and then continued.

"I don't know, but one day, she just told me to stay in the classroom after the class ended, and then she kissed me out of nowhere.

"Sure, I can be considered handsome, but have you seen her? She is a complete knockout, so honestly, it was pretty amazing, but I don't know why she would do that with me…

"I thought that she must've been some maneater or something, and I, for a moment, thought that she was doing the same with other students too."

With a cough, Jeff excused himself to get another drink. He poured water into a cup, drank it all, and returned to the table.

"Your health started worsening after you started doing that with her?"

Kael asked.

"Uh, I don't know… I've been feeling pretty good till now, and sure, after doing the deed with her, I did feel pretty exhausted, but I thought it was normal."

Jeff said.

"Hmm…"

Kael thought sarcastically for a moment that Jeff must've just been sucked dry, but he decided not to say it out loud, as this wasn't a joking matter.

He didn't need to be a medical expert to know that he was far from being fine.

At that moment, a room door across from the kitchen opened, and in only a gray shirt and underwear, a girl walked in.

She looked to be sweating, had her hair in a messy bun, and just poured some water for herself.

"Uhh…"

Kael looked at her with a raised eyebrow, thinking that she might not have noticed them, just like he didn't notice Jeff at first.

It sure was quite dim, so it could've been a possibility.

However, Hazel just turned to look at them, drank the water, and then returned back to her room, where there was someone else.

With a slight glimpse, Kael could swear that Owen, one of the students, was lying shirtless in Hazel's bed.

It looked like Jeff and the teacher Angelica weren't the only couple tonight that was doing some private activity.

"T-they aren't a couple, either. It's just something that the two of them do for fun as stress relief, you know, as this world can be quite stressful…"

Jeff said with a pained tone, coughed one more time, and this time, he coughed some blood onto a napkin.

"Fuck…"

He cursed.

"I think you need to consult a doctor about your condition, and I think you need to stay away from Angelica."

Kael said.

"W-why…? You think that she is responsible? W-why would she want to hurt me? It doesn't make any sense, as she is a teacher…"

"I've read some novels, you see. About women who suck the life force of young men to make themselves prettier and stronger."

Kael said with a chuckle, then saw that he wasn't much in a joking mood, and thus, he put some more serious tone into his voice.

"At least till you get checked out by a doctor, alright?"

"Sure thing…"

Jeff climbed back to his feet, said good night to Kael, and then headed back to his room to get some good night's sleep.

'I don't know what is going on with him, but why do I feel like Miss Angelica is responsible? She is an incredibly beautiful woman, and it's no wonder that Jeff is completely swooned by her.

'And from the conversation I heard back then, she seems to consider him as some loyal dog that follows everything she says.

'I don't feel any love from her. Lust, maybe, I don't know, but if that's all there is, she would've probably tried to make a move on other students.

'It would help if I knew what her class is. I know that she is supposed to be a Magician, so maybe if I know her class name, I can tell whether she is responsible.'
