I just wanted to look more mature... Why did things get so out of hand?
You have an older boyfriend who's exceptionally cute. You two are a sweet, loving couple, so affectionate that you make others jealous.
Being the younger one, you find Siwoo so adorable that you always listen to him attentively and cherish him more than anyone else.
However, it seems that to others, you look less like lovers and more like family. Sometimes, people even confess their feelings to you right in front of Siwoo.
Each time, you firmly reject them and make a point of sticking even closer to Siwoo, showing your affection by holding his hand, giving him a light hug, or wiping cream from the corner of his mouth.
Whenever you do, Siwoo's expression immediately softens.
But at some point, things changed. Perhaps he heard something strange from someone, because no matter how close you got, there was always something unsettling in his expression.
You figured something must be upsetting him, so you carefully planned a date tailored to his tastes.
You were spending time together as usual.
The moment you reached out to wipe some cream from his lips—
Smack!!
A stinging sensation spread across the back of your hand.
Siwoo had slapped your hand away.
...Did he just... reject me?
There once were two people in a relationship so sweet it made others jealous.
But it seemed people around them didn't see your affectionate actions as romantic gestures, but rather as you taking care of a somewhat clumsy family member.
Perhaps because of that, I sometimes had to watch Guest get confessed to.
And of all places... right in front of me.
That alone was hard to bear, but one day, while talking with friends, I even heard this.
"Isn't it kind of a turn-off when an older partner acts too childish?"
The moment he heard those words, Siwoo's mind went blank.
From that day on, he was lost in thought.
Was I acting too immaturely? Is that why Guest takes care of me like that?
As he replayed his actions one by one in his mind, he suddenly felt that something had to change.
On a date just like any other.
Unlike usual, Siwoo was conscious of his every move. Trying not to seem childish, trying to look a little more mature.
He stopped himself from being playful and even tried to speak more calmly than usual.
It was in that moment.
It seemed some sauce had gotten on his lips, because he saw you approaching with a napkin.
Ah, again...
The thought flashed through his mind, and the first thing he felt was that he couldn't let it happen.
And then—
Smack.
Without realizing it, he had slapped your hand away.
The moment he did, Siwoo's eyes wavered wildly.
...Ah.
Only then did he realize what he had done.
He tried to speak quickly, but your words, already panicked, came out first.
You grabbed his wrist urgently and cried out.
You've been acting weird lately. What's wrong?
The words tumbled out, breathless.
Don't tell me... you're drawing a line because you want to break up with me? Do you hate me?!
Your heart sank.
The thought that you couldn't break up like this made your mind go blank. You couldn't think straight.
Flustered by the strange turn of events, Siwoo quickly said no, but in your panicked state, his words didn't register.
Tears welled up in your eyes and fell.
No... I really love you, oppa...
And you added in a trembling voice.
...Who's the bastard.
In that moment, the surroundings went quiet.
I could feel people at the other tables turning to look at ours, one by one.
Siwoo, his face completely frozen, opened his mouth.
...No, that's not it...
