Hearts2Hearts “15-LOVE” Lyrics

Hangul

Ayy, you wanna, you wanna
You wanna, you wanna get it like
Ayy, you wanna, you wanna

예고 없이 짠
시작돼 버린 이 게임을 즐기고 싶어
부쩍 내게 덤벼드는
널 괴롭힐래
뭔데 너 왜 당연한 듯이
내가 널 받아줄 거라 생각해?
Throw that ball from left to right
어디든 날려봐

너와의 매일이 랠리, 늘 이렇게
달콤한 맛이 나는 것 같아
Ready, set

Poppin’, poppin’
튀는 내 마음 던져
Shooting heart, hit you right, 널 흔들고
That fifteen love
닿을 듯 말 듯
했던 내 마음 놓친
지금 넌 여전히 L-O-V-E야
That fifteen love

Bounce that ball, bounce that ball, hit it
Fifteen love, fifteen love, get it
Bounce that ball, bounce that ball
I’ma get that fifteen love
가끔 엇갈리는 리듬 위
우린 꼭 shuffle dance를 추는 것 같아
포기하진 마
그럼 열기가 식잖아

심장 소리는 두근
내 코는 찡긋
툭 웃음이 터지기 직전
Ready, set (Ah)

Poppin’, poppin’
튀는 내 마음 던져
Shooting heart, hit you right, 널 흔들고
That fifteen love
닿을 듯 말 듯
했던 내 마음 놓친
지금 넌 여전히 L-O-V-E야
That fifteen love

솔직히 말해
이 code 위 네 모습이
난 딱 좋아
끝내고 싶지는 않아 (Ah)
솔직히 말해
이 code 위 네 모습이
바로 지금 너의 상태
그대로 있어 줘

Round (Round), 우리가 펼칠 round (Round)
주고받는 마음의 sound (That sound)
이다음, 넌 어떻게 내 마음을 뺏을까
Woah, ooh
Don’t stop, yeah (That fifteen love)
알 듯 말 듯 했던 너의 진심을
또렷이 느끼는 바로 지금
That fifteen love

Translation

Ayy, you wanna, you wanna
You wanna, you wanna get it like
Ayy, you wanna, you wanna

Without a single warning, ta-da!
I want to fully enjoy this game that has suddenly kicked off
You’ve been stepping up to challenge me so much lately—
I think I’ll tease and trouble you a bit
What’s your deal? Why do you act as if it’s completely natural
To assume that I would just willingly accept you?
Throw that ball from left to right
Fire it off wherever you want

Every single day with you is a rally, always playing out like this
I feel like it carries such a sweet flavor
Ready, set

Poppin’, poppin’
I throw my bouncing, leaping heart
Shooting heart, hit you right, shaking you completely up
That fifteen love
Seeming like it’s just within reach, yet just out of touch—
You completely missed my heart,
And right now, you are still stuck at L-O-V-E (zero)
That fifteen love

Bounce that ball, bounce that ball, hit it
Fifteen love, fifteen love, get it
Bounce that ball, bounce that ball
I’ma get that fifteen love
On top of a rhythm that occasionally falls out of sync,
I feel like the two of us are definitely dancing a shuffle dance
Don’t you dare give up just yet—
If you do, the feverish heat will cool right down

The sound of my heart goes pit-a-pat,
My nose crinkles up playfully,
Right before a sudden laugh goes bursting out
Ready, set (Ah)

Poppin’, poppin’
I throw my bouncing, leaping heart
Shooting heart, hit you right, shaking you completely up
That fifteen love
Seeming like it’s just within reach, yet just out of touch—
You completely missed my heart,
And right now, you are still stuck at L-O-V-E (zero)
That fifteen love

To be completely honest with you,
Seeing the way you look on this court (code)
Is absolutely perfect to me
I don’t want this match to end just yet (Ah)
To be completely honest with you,
Seeing the way you look on this court (code)—
Your exact emotional state right now,
Please just stay exactly like that for me

Round (Round), the round that we are about to unfold (Round)
The sound of our hearts passing back and forth (That sound)
Right after this, how exactly are you going to steal my heart?
Woah, ooh
Don’t stop, yeah (That fifteen love)
Your sincerity that previously seemed clear yet vague—
I can feel it with absolute clarity right this second
That fifteen love
