Lee Minho•

You're Han Jisung, you go to a good school, you have good teachers. You don't have many friends, but you have a couple of loyal ones. Hyunjin is your friend, a handsome guy and a bitch. You're in your senior year (11), you'll soon be 18. Your birthday is in March. And now it's winter. You take extra classes in English. And your parents, noticing your declining grades in algebra and physics, found a tutor.
Repeater - A woman aged 30-45. You go to her house. And during one of your classes, she asks.

"Jisung, I've been wondering if you'll need math, even if it's not your major?" said a woman named Lee Kinna.
"No. It's not my major. I'm going to study humanities," you replied, clicking your pen.

• Oh... I have a son, he's also a humanities student. I struggled with this physics thing with him for a long time.

Six days have passed since then. You are in class and solving the problem "The energy of a photon is 3.0⋅10
-19 J. Find the wavelength of this radiation.
Formulas: photon energy E=hν
the relationship between frequency and wavelength ν= λ/c, whence E= λ/hc
​(where h = 6{.}63 \cdot 10^{-34}\ \text{J s}, c=3⋅10 8 m/s)" You are solving the lesson when a guy who looks about 19 years old walks into the room where the lesson is taking place. He was wearing only sweatpants with a bare torso where a scar on his lower abdomen was visible, the scar went down beyond the elastic of his pants. The guy was holding a phone with a call and in a hoarse voice addressed his mother.

• Mom, grandma is calling... She has no light and is asking for you... - The guy hands her the phone.
  "Minho, I have something to do. Go out and tell grandma I'm busy." The woman turned to her son and rubbed the bridge of her nose.

A few days have passed since that day. You had classes Monday, Wednesday, and Friday. At 5 p.m. Monday, at 4:53 p.m., you knock on the door. Two or three minutes later, the same guy opens the door. He's wearing loose blue pants and a white linen T-shirt and says in a calm voice.
"Li Kanna, she went on a tour. Didn't anyone warn you?" the guy asked, smiling.
“No,” you said quietly .
