OwO encontré la traducción en inglés de la canción que necesitas, la revisé de manera muy breve comparando el haponés con el inglés ^^ y creo que te servira, si necesitas que te ayude a traducirla a español avisas XD
When I'm frustrated with myself and biting my lip,
I try mumuring that name of yours in my heart
When it's as if I can't look at anyone and I'm wiping my cheeks
I secretly picture that smile of yours
You're my beloved, from the bottom of my heart
I'm lost near a summer that's continuing on to the unknown,
heading to a distant place
But me, I'm not afraid at all
I'll give you this, from the language of flowers
n this pale, pale jasmine,
there are strong, strong memories
Any time you look up, it says
"I'll always follow you."
When I'm cold and hurting and things suddenly collapse,
you're the only one who still recognizes me then, right?
I think you're a kind person, from the bottom of my heart
Today is always scattering to the winds
and the path of my memories is fading
But me, I'm not lonely at all,
because that's unquestionable proof
The rain runs too quickly,
and the scent of the steamy air rises
to the impossibly, impossibly far-off sky
I'm lost near a summer that's continuing on to the unknown,
heading to a distant place
But me, I'm not afraid at all
I'll give you this, from the language of flowers
In this white, white jasmine
there are deep, deep memories
At any time, at any time, it says
"I'll always follow you."
