Chapter 1

From: Unknown.
"Is it true that Professor Johnson wears checkered underwear?"

What?
Eren frowned as he narrowed his eyes on the message he had just received a few moments ago. He did not recall recently giving his phone number to a stranger, or having a friend who was interested in the underwear of his sixty-year-old professor of marketing basics.
He looked back at the fading screen, and the message remained as it was.

To: Unknown.
"Why are you interested in the underwear of a sixty-year-old?"

As his finger clicked the send button, Eren wondered why the hell hadn't asked for the identity of the caller.
But it was too late to delete the sentence the person on the other side had probably already read.

He waited, staring blankly at the phone screen, his legs drilling a hole in the mattress. But when, after a good three minutes, there was still no answer, he put the phone down on the dresser next to the bed and dropped his head down on the pillow.
He was already reaching for the lamp's light switch when the notification sound was heard in the room.

From: Unknown.
"I'm just wondering. Women her age often wear such underwear. "

He decided to let go of the question of how the person on the other side knows what the lingerie trends are among older women.
Eren sighed in annoyance.

To: Unknown.
"When I meet you tomorrow, you have a hard time, horsehead."

From: Unknown.
"Then I'm so glad I'm not a horse's head."

- What the hell? - Eren grunted under his breath, rubbing his eyes, tired with the whole day of studying.

To: Unknown.
"Then who the fuck are you ??"
"Annie, you're not funny. You know I have a colloquium tomorrow, so fuck off. "

Silence.

To: Unknown.
"Annie?"
"You don't really sound like a woman, so maybe ... Ymir ?!"

From: Unknown.
"From what I know, Ymir is a woman's name, brat."

- Little brat ?! he snorted softly, disbelief.

To: Unknown.
"You know Johnson, so you can't be more than two years older. If I'm a brat, so are you! "

From: Unknown.
"How can I be sure that I am not, for example, a graduate? Or another professor? Or a stalker? "
From: Unknown.
"If it comforts you, you were right. I'm not a woman. "

- Ha! I knew!

A knock on the wall interrupted the stream of riposte throwing him at the keyboard.
- What did you know, Eree ... - yawning. - .. een?

Armin.
- Nothing like that, Armin. I'm sorry if I woke you up!

From: Unknown.
"You got scared, kid. I don't think I'm playing a stalker. "

- I haven't slept, don't worry! Haikyuu chapter came out today, you know I couldn't miss ... - Armin replied, lighting the night with his laugh. Eren loved the sound. Every time he heard him, the happiest moments of his life would come to his eyes.

From: Unknown.
"Oi, kid."
"Did you fall asleep?"

- Come in the morning at nine, maybe we can read it again before the lecture. he replied to his friend, with one eye looking at the illuminated screen of the phone.
- Good night, Armin

- Don't stay too long or you'll be sleepy! Armin warned in a muffled, probably through a pillow, voice.

To: Unknown.
"I spoke to Armin."
"Why am I actually telling you about this?"
"You can be anyone."
