My Beautiful Disciples, I'm really not the Main Character!

"Son—" The woman grabbed Eren's hand. However, before she could even complete her word, Lysander appeared behind her and covered her mouth.

"Hahaha, it's her first time seeing someone from Earth other than me, so she's a little curious," he laughed awkwardly, offering an explanation to his daughter.

Immediately afterward, he brought his lips close to his wife's ear and whispered, "Don't say anything, or the wedding will end before it even becomes possible."

The woman bit her husband's hand, making him release her. She was a little confused about his reason for silencing her, but the potential consequences made her comply.

"My dear daughter, you are back from a long journey. Why don't you go and rest? We have some things to discuss with him." He jerked his hand, which still had the bite mark.

Estelia looked at her parents, who were behaving strangely. She didn't understand why, but she nodded. She freed her hand from Eren's hand and started walking away.

On her way back, she occasionally glanced back, wondering what they had to talk about. At first, she had thought that Eren was only a guest that came from the same place as her father, which was why he was accepted.

However, the more she interacted with him, the more incomprehensible he appeared. He didn't look like someone who had come from a peaceful world. Even his strength wasn't much weaker than her based on her limited interaction with him.

At times, she even felt that he might be able to defeat her if he didn't hold back. But she couldn't be certain about it, as it was just a feeling. Unless she fought in a life or death battle with him, it was impossible to confirm.

She soon walked through the door, and disappeared inside the palace.

....

"Are you going to tell me what this was about?" The woman asked Lysander, glaring at him.

It was the first time Eren had seen someone as powerful as Lysander being drenched in cold. He might be the strongest existence in this world as a demigod, but the woman was even stronger.

If anything, the woman reminded her more of the goddess of light, giving the same suppressive feeling. She was not just a demigod but something beyond.

Lysander cast a sound isolation barrier around them, even after confirming that his daughter was not here.

Once the barrier was completed, he started telling his wife everything, including his deal with Eren. He didn't forget to complement Eren as the best son in law that they could have found, which made him take this step.

The woman silently heard her husband's explanation as she looked at Eren. Eren gulped down, feeling like a specimen under a microscope.

He didn't feel this suppressed even under Lysander. He wasn't even sure if he had any possibility of escaping from this place, at least not unless he was able to successfully use the echo of eternity.

He had only killed a god once in his life, that too when he was under the effect of echo of eternity.

Unfortunately, even he didn't remember anything from that time, not even knowing how he had killed the goddess of light. If possible, he didn't want to take that gamble here.

"So your name is Eren?" The woman asked once the explanation finished, as her gaze narrowed.

Eren nodded, wondering what that woman might be thinking about.

"Why do you look so nervous, as if you did something wrong?" The woman frowned, her gaze sharp enough to make Eren feel completely exposed.

"It's my first time meeting you, Mother-in-Law, so I am a little nervous," Eren answered, taking a calculated risk with his words. "After seeing you, I finally understand where Estelia inherited her beauty."

"You brat, are you calling me ugly?" Lysander's lips twitched.

"Not at all. It's just that Mother-in-Law is so charming. If you hadn't introduced her, I would have thought she was Estelia's older sister." Every woman loved a compliment, or at least that's what he had heard, and he put this saying into action.

"Looking at both of you, you two seem like a match made in heaven." He didn't forget to make it clear that he wasn't flirting with Lysander's wife, bringing him into the picture as well.

While complimenting her, he carefully observed even the smallest reaction. Unfortunately, there was nothing. She remained silent, showing no outward response.

He wondered if he had made a mistake. Had he overplayed his hand? He couldn't be certain.

"Did you hear what he said?" Her cherry lips moved as she turned to her husband. "He called me Mother-in-Law."

Her lips slowly curved into a smile. The words sounded so pleasant to her. She had imagined many times that her daughter would find a life partner and that she would be called "Mother-in-Law" by that person. Now that it had finally happened, it felt surreal.

Eren had expected the compliments to work on her. Surprisingly, what resonated wasn't the flattery, but the same title that had worked on Lysander.

He didn't show his true emotions on his face, but deep down, he was amazed at how simple these two powerful beings were. They truly loved their daughter so much that they seemed to have been worrying about her future for a long time.

If he didn't know better, he would've thought they were a little crazy. Then again, he still couldn't completely dismiss that possibility.

"He is so nice. Do you see how he complimented me? Why don't you learn from him?" she asked her husband, who scratched the back of his head.

The woman turned back to Eren, not even waiting for her husband's reply. "Son-in-Law, you were holding my daughter's hand. Have you two started to accept each other? When can we arrange the wedding?"

"I fell for her a long time ago. I'm just trying to show her my sincerity so she can also accept me."

Eren hadn't wanted to say that he was prepared for a wedding in the near future, or even to give them false hope, but it was already too late. He wasn't sure what the woman might do if he continued to give vague answers.
