He got up from the sofa with the empty cup, made up a random excuse, and wanted to leave for a while:

"That... well..."

"I'll go heat up another cup of milk."

Before he could leave, Ai's cool voice rang out from the side:

"Heat me a cup too."

"Um."

He quickly replied, grabbed another cup, and headed to the kitchen.

He didn't look at Ai even once during the whole process.

If he were to see it, he would discover:

On the face of the owner of that cold voice, however, hung a smile that did not match the calm tone.

Ai didn't look away until Kōyū walked into the kitchen.

She pursed her lips and murmured to herself:

"This guy..."

"Weren't you just now going to continue in front of your sister?"

"Why are you leaving so soon?"

There seemed to be a hint of resentment in her cool voice.

Not exposing him is giving Guangyou a chance to continue.

But Kuang-Yu didn't grasp this meaning.

If Kōyū knew, he would definitely sigh:

What a pity!

For a moment, only Ai was left in the living room.

She leaned back on the sofa, her gaze seemingly flickering slightly in the lamplight:

Not only Mitsuyu, but Ai also had other thoughts on her mind at this moment:

There are love letters, and there are also letters that Kwang-woo wants to "ambush".

She thought to herself:

"He's done this so many times."

"It's time to settle accounts with him."

As she imagined what was about to happen, a faint blush crept onto Ai's cheeks, but quickly faded away as if it had never happened.

"Ding~"

In the quiet apartment, the crisp sound of the microwave oven was easily noticed.

Ai, who was thinking about the contents of the love letter, slowly opened her eyes after hearing this, revealing her beautiful ice-blue eyes.

After a period of calming down, Kōyū finally stopped caring that Ai had seen through his intentions.

If this sneak attack fails, then we'll wait for the next one.

If it fails next time, then try again the time after that.

In any case, there will be a success eventually.

His success rate in sneak attacks used to be 100%!

This time, Ai saw through my disguise, which is a good opportunity to learn from the experience.

Try to act more naturally next time.

Don't let your mood be low for no reason or show that you have something on your mind.

He walked to the sofa with a normal expression and placed the milk on the table in front of Ai.

Then, he sat back on the sofa, took a sip of milk, and thought to himself in a very Zen-like way:

"Next time."
