Five years later.

Yoon Jae woke up at 6 a.m. and stretched.

Though it was vacation and there were no classes, as a physical education student, he always ran around the neighborhood at this time.

Today, he left the house with a fresh mind, planning to exercise as usual.

And immediately rang the doorbell of the house next door.

It was to wake up his comrades for the morning exercise.

After ringing the bell three times in a row, the door opened.

But no one was seen, and the door started to close again.

Yoon Jae quickly caught the door.

Feeling something strange and stepping inside, he saw the disastrous living room scene.

“Ah, these people really…”

Ignoring the two women collapsed on the floor, beer cans and snack bags were strewn about carelessly.

Wondering until what time they had drunk, the women were lying as if dead.

Yoon Jae, who counted up to eight empty cans, gave up and woke the two women.

“Kang Ji Woo! Lee Sa Rang! Wake up quickly.”

Ji Woo and Sa Rang had joined Seohan Electronics, the envy of engineering students, right after graduating from college.

Thus, the two became inseparable friends, sharing schools from elementary to high school, college, and now their workplace.

Moving from a one-room near the school to a two-room near the company, they enjoyed a free life for a while.

With the exhausting job preparation over and a steady salary from the desired company, they couldn’t be happier.

Of course, the work was hard for what they earned, but their loyalty exploded on payday, swearing allegiance to the company.

However, this lifestyle lasted only a year, sadly.

Yoon Jae, who had been dating Ji Woo for three years, suddenly moved into the next door one day.

At the same time, their glamorous solo living came to an end.

Being a former athlete, Yoon Jae’s day moved according to a fixed schedule.

Thanks to him, they were forced to maintain a correct lifestyle.

Even on days like today, when they had drunk till dawn and passed out.

“Aren’t you going to work?”

At the robust voice of Yoon Jae, Ji Woo and Sa Rang wriggled like caterpillars.

Wondering what time it was for such a commotion, Ji Woo barely opened her eyes to check her phone.

“Ah, what. It’s only 6 o’clock…”

Regret for opening the door flooded her.

Since they had to go to work by 9, waking up at 7 was sufficient.

As Ji Woo closed her eyes again, Yoon Jae, cleaning up the trash, came over, grabbed her arm, and sat her up.

“Shouldn’t we go out for exercise?”

“Hey! Humanely, let us off just today.”

Ji Woo frowned.

Even though he was her boyfriend, it was too much.

How could he go out for exercise every day at 6 without missing a day?

It was fine up to that point, but why did they have to join as well?

Although she was attracted to Yoon Jae, a rarely upright man, and started dating, being neighbors revealed that an upright lifestyle wasn’t all good.

Sometimes she wanted to stay out with friends and drink all night, but Yoon Jae was stricter than her parents.

“Who told you to drink until late? It’s not even the weekend, what are you planning in this state?”

“Alright, alright. I won’t do it again, so let’s just skip today. Sa Rang can’t even get up.”

Unable to lie back down because Yoon Jae was supporting her back with his legs, Ji Woo sulked.

Next to her, Sa Rang was still sleeping, oblivious to the world.
“Hey! Lee Sa Rang! Wake up right now!”

Startled, Sa Rang sluggishly sat up.

“Ah, Jung Yoon Jae, really. Why are you like this? Just do a lot of exercise yourself. I don’t need to, okay?”

“The weakest one here is talking. It’s because we at least run around the neighborhood in the morning that you guys can drink till dawn.”

“Kang Ji Woo, just go and live far away with Yoon Jae. I’ll just live alone.”

Complaining from the morning, Sa Rang struggled to get up.

It was even bothersome to talk.

“What terrible things to say. I’d rather commute from my parents’ house than live with him.”

Ji Woo was so annoyed that she even mentioned her parents’ house, which took over three hours by bus.

Then, feeling a sting on her head, she looked up to find Yoon Jae glaring at her.

Oops. He was my boyfriend.

Briefly forgetting, Ji Woo flashed an awkward smile.

Sa Rang, sensing the tense atmosphere, quickly retreated to the bathroom.

“What, what did we eat so much of?”

Trying to clean up the mess, Ji Woo quickly got up, but Yoon Jae held her back.

Unable to meet his seemingly angry gaze, Ji Woo turned her eyes away.

“Do you hate that much that I live next door?”

“Huh? Oh, no. It’s not that…”

“If it’s that, I’ll move out.”

“No. It’s just something Sa Rang said. I’m sorry. It’s my fault, okay?”

Ji Woo hooked her arms around Yoon Jae and half-closed her eyes.

She didn’t want to go to work after fighting with her boyfriend in the morning.

“I’ll clean everything here, so don’t even lift a finger. I really won’t do it again.”

Usually, he would have softened by now, but Yoon Jae’s expression remained unchanged today.

Worried that her words had been too harsh, Ji Woo looked downhearted, when suddenly he kissed her.
