It later appeared in the shoujo manga "L?DK" (Neighbors? Cohabitation) by manga artist Ayu Watanabe.

Then, through its adaptation into a film, it quickly became known to the public.

In this era, "wall slam" is still a very unfamiliar term; no one has ever used it.

In the current situation, Kōyū couldn't explain too much, so he could only explain it to Ai in the simplest and most direct way:

"Sofa-thump" is what we're doing right now.

"Wall slam is just replacing the wall with a wall."

"I see."

After Kōyū said that, Ai's inner tension inexplicably eased a little.

As Guangyou felt his breathing become somewhat erratic, and his cheeks unusually flushed, he asked again:

"Ai, what are you thinking about?"

When faced with Kōyō's question, Ai didn't answer directly, but instead brought up something from the past:

"I remember you've ambushed me many times, haven't you?"

Even though Ai asked a question that sounded like she was going to settle accounts with him, the atmosphere at that moment made Kōyū feel that there was no sense of "settling accounts" between them.

But he had the same reaction:

My heart is racing, and I feel nervous.

The difference is:

He was still a little excited.

Under Ai's gaze, Kōyū nodded:

"Um..."

"Many times."

Upon hearing Kousuke's admission, Ai bit her lip lightly, hesitated briefly, and then said:

"In that case..."

"I also..."

The conversation ended there.

Her personality prevented her from saying something as blunt as, "I'm going to ambush you too."

But Kōyū already understood what she meant:

"So you want to..."

Before he could finish speaking, Ai suddenly asked again:

"If I don't say it..."

Does it count?

Hearing her self-deceiving words, Kwang-woo readily gave an affirmative reply:

"Calculate."

I think so.

Both of them knew in their hearts that this could no longer be considered a "sneak attack".

His words were just a psychological comfort.

But clearly, this statement had an effect.

Despite her shyness making her want to avoid Kousuke's gaze, Ai still looked at him, though her eyes kept drifting to the sides.

She spoke to Guangyou in a voice barely above a whisper:

"Close your eyes."

Without a word, Kwang-yu slowly closed his eyes.

After Kōyū closed his eyes completely, Ai slowly closed the distance between them.

at last..

The two of them tasted a faint milk flavor.
