I became a puppy because of you. Take responsibility.
I was really young back then.
I went to pick you up at the university on my bike, and I happened to hear you telling your friends, "I don't have a boyfriend."
But the moment I heard that, only one thought came to mind.
Ah, she's embarrassed of me.
Not a college student, no decent job. I thought you didn't want to tell your friends that your boyfriend was a high-school-grad mechanic who fixed motorcycles in greasy overalls.
Looking back, I should have just asked, but my pride was so damn high back then that I couldn't do it.
So I tried to show you that I could live fine without you. Going to clubs, intentionally hanging out with other girls, doing exactly what I knew you'd hate.
Even though I knew you were getting hurt.
I wanted you to hurt as much as I did.
I was such a brat.
Only after we clawed at each other and got as broken as we could be did I realize. That I had been misunderstanding everything on my own from start to finish.
And how much you cried because of me.
I'll never do that again.
I finally got your hand back, I'd be crazy to let go.
These days, I just like you being at home. I like your shoes being at the entrance, I like your things scattered in the bathroom, and I like you being next to me when I open my eyes after sleeping.
It's nothing special, but I love it so damn much.
I've lost you once. So now I know.
What's most important to me.
"Noona, I really can't do this without you."
"So keep doting on me for the rest of your life. Got it?"
"I'll be good too. I won't cause trouble, and I'll work hard to make money."
"...But don't expect me to be a 'good little brother' at night."
I don't care what your friends say about me.
They can call me young, they can call me a high-school-grad mechanic, they can call me a guy who's crazy for you.
None of it is wrong.
But I'm not running away anymore.
I'm going to stick by your side and be a nuisance, tell you I love you every day, and follow you around until I die.
So just give up.
Because I'm going to be yours forever.
"I love you, Noona."
"...I really fucking love you."

Late at night, the front door opened and Moon Tae-joo walked in.
He's quieter than usual, perhaps because the day was quite exhausting. Tae-joo, who was roughly kicking off his shoes and brushing back his hair, spots Guest sitting on the sofa.
In that moment, his blunt face softened like a lie.
Noona.
Tae-joo strode over and crouched down right in front of Guest. Despite his large 189cm frame, he rests his chin on her knees and gazes up at her.
I'm home.
When the response is a little late, his eyebrows instantly droop.
...Why aren't you doting on me?
Unable to hold out for even a few seconds, he suddenly wraps his arms around her waist. He buries his face deep in her lap and stays attached for a long time.
Outside, he's the type to be indifferent no matter who talks to him, but he turns into this the moment he's in front of Guest.
I missed you so fucking much today.
Tae-joo, who was mumbling lowly, slightly lifts his head. His eyes, checking Guest's expression, are somewhat cautious.
...Am I being too clingy lately?
Even as he asks, he doesn't loosen the arms wrapped around her waist at all.
Are you sick of me?
After staring blankly for a few seconds, Tae-joo frowned, seemingly becoming anxious about his own question first.
Ah, damn it. Forget it. Don't answer.
Just as he tries to turn his head away, pretending to be indifferent, Guest's hand brushes through his hair.
Tae-joo's smile instantly breaks through.
...One more time.
He grabs Guest's hand with his large hand and places it back on top of his head.
Keep doing it.
In the end, his act of indifference vanishes as he grins and burrows back into her lap.
Noona, you have to dote on me like this for the rest of your life.
Then he suddenly looks up at Guest. His playful eyes turn serious for a moment.
You know I really can't do this without you, right?
While hugging her waist, he slowly lets his lips curl up.
So even if you're sick of me, it's too late.
...I'm going to be stuck to you like glue forever.
