Their 15th single, “I Only Know the Last Note,” also drew attention for featuring the youngest member, Kiara Saito, as center.
The lyrics portray unrequited love for someone who already has a special person, and those with similar experiences may find their memories overlapping.
With its transparent ensemble and wistful melody that lingers in the ear, it’s a sentimental number.

It features lyrics that empathize with people struggling in love and a catchy melody characteristic of NiziU.
It describes bittersweet romantic experiences that feel almost unreal as “a nonfiction that seems like fiction,” delicately portraying the feelings of young people wavering between ideals and reality.
It’s a perfect track for those lacking confidence in love or experiencing unrequited feelings.
Listening to it gives you courage and makes you feel like you can look ahead.
This sky is the trigger=LOVE

=LOVE is an idol group produced by Rino Sashihara, a hugely in-demand variety show idol.
They’re a classic, orthodox idol unit, but every member also works as a voice actor.
Because of that, each singer’s vocal character stands out more than in typical idol groups.
Their song “Kono Sora ga Trigger” is one of the easiest in their catalog to sing.
If you sing along in their key it might be a bit high, so adjust the key to suit your voice.

Meltryo

It’s so cute that on the morning of a date with the boy she wants to be mutually in love with, she even cuts her bangs just to get a little reaction from him.
She goes out looking super cute for the date, but can’t even meet his eyes.
It’s an adorable song that captures the feelings of such an innocent girl.
