Tankhun is Macau, dad's best friend son. Also, he took over his(Tan) dad company . Here, Macau is doing his 2nd year in business he really good at everything, but only weak in math, so Macau's dad asks Tan to teach him. He also agreed with that.

Tan started teaching him in his own house where he lived alone, so he asked Mac dad to move Max with him as it will easy for them also the college is near.

Everything was great. Mac showed some improvement in his tests. It is almost the year end before the semester they had some tests. All of sudden, Mac can't able to concentrate because of the main exams' fear, and also he feels mentally tired as they have a lot of test and project. So he scored very less in this test.

Tan : What the hell is this Mac? What score is it? If you continue like this, you will be failed in this year!

Mac : it's not like that, Phi... it's just I'm....

Tan doesn't let him complete his sentence.

Tan : Don't give a reason, Macau. Go and bring your questions paper in 5 minutes. * serious tone *

Macau just went and brought his questions paper and gave it to Tan.

Tan : I will give you time 45 minutes to go through these questions. After that, I will ask you questions you should answer correctly. If you don't, you will fave the consequences. Understand.

Macau got really scared, so he went to go through it. After 45 minutes, Tan asked him to come near him.

Tan : Are you ready? The first question. If x + 5 = 11, what is the value of x?

Mac : it's... 6.

Tan : Good. The next one z: z/4 = 9?

Mac : z = 36?...

Tan : Nice, find the derivative of f(x) = 3x^2 + 2x. You can solve and answer this. Here is the notebook.

Mac tries to solve this, but he can't.

Mac : f'(x) = 8x + 2 * hesitate *

Tan : How will it be an 8? Show me your hand. * Then he hit with a scale*.

Macau tears up.

Tan : the next one . A company's average sales are ฿ 50,000 per month. If the sales for 5 months are ฿ 45,000, ฿ 55,000, ฿ 50,000, ฿48,000, and ฿52,000, what are the total sales for these 5 months?

Mac : * tries * I'm not getting the answer, phi.* sobbing little *

Tan again hit him twice. Mac should because of the pain.

Tan : If an investment earns a 10% annual return, how much will 1,000 Thai Baht (฿1,000) grow to in 2 years?

Mac : ฿1,210

Tan : right answer.

There is 50 a question , Mac answered for 27 and 23 wrong. So he got 23 minutes, sometimes twice in it. And not only on his hand, but I'm his thigh. Usually, Tan won't be this much strict, but he really had a bad day. When he git to know Mac doesn't scored well, he gets super angry and lets it out on Mac.

After the session over, Mac went to his room and went to his room. Mac locked himself in his room and cried a lot. He stayed in his room for the next 2 days. As it's weekend their is no math session. Tan doesn't know this because he had a work. When Tan got back from work, the maid informed him that Mac had not come out of his room for 2 days. He got worried and guilty. When he shared this incident with his best friend , he got scolded from his saying Mac, just a kid, a d this is his first why can't you give a chance, and if his big brother got to know this your death. So he went straight to Mac room and knocked it.

Tan : Mac, please open the door.

He got no response he knocked again, but still no, so he got scared and opened the door with a spare key. When he went inside, his guilty got all over his body because Mac got pale, and it looked like he cried a lot when he touched him, Mac is burning in fever so called his personal doctor. Later, when the doctor came.

Dr. He just has a fever, but it looks like he didn't have proper food. Also, he has some marks on his body, so please look at what it is. Give this tablet and give him something healthy.

He said and went out. Hearing this, Tan got more guilty, so he went close to Mac , held his hand, and touched his cheeks.

Tan : Mac, baby please phi is sorry. I won't do it again. I'm just stupid to do that. Please wake up. * crying * ( he loves Mac, but don't confess he waits for Mac graduation)

Mac doesn't wake up. After 2 hours, he wakes up. He saw Tan hold his hand. He took his hand, and this action made Tan wake up.

Tan : baby, you wake up * he tries to touch *

But Mac got scared, so he flinched so hard . Seeing his Tan heart got broken. He tries to comfort him, but it makes worse, so he asks the maid to come take care of him. When he again sleeps, he goes towards him and kisses him on his forehead. Flowing days, Mac got so silent that he just went to his class and said that he was not being himself like before like a happy kid. Mac really becomes so silent. it's likely he doesn't speak a word.

It's been a month since the incident happened. Tan tries his best to make him like before. It's took 3 weeks to make him not scared, but still, Mac is not letting him near or touch him. But one day, suddenly, Vegas comes to visit him.
