You, him, me, and herBreathe

An R&B ballad in which BREATHE delicately sings about those wavering feelings of “I thought we were just friends, but I fell for you.” Set within a love square where both parties already have partners, it portrays the conflict between newfound feelings and moral hesitation through scenes like late-summer rain and sharing a single umbrella.
Released in May 2014 as the B-side to the single “Tomorrows,” it was also used as an ending theme for the TV Tokyo anime FAIRY TAIL.
The lyrics were written by Kiyoshi Matsuo, and the harmonies of Satoshi Miyata and Kazuya Tada bring the nuances of emotion to life.
It’s a song that will resonate with anyone torn between friendship and romance or carrying feelings they can’t put into words.
I got a boyfriend/girlfriend.My Hair is Bad

How would you feel upon learning that someone you once shared a deep connection with has found a new partner? My Hair is Bad’s 2016 album “woman’s” features a song that delicately captures exactly that complex state of mind.
Even though you’re supposed to have moved on and found a new lover, you can’t shake the lingering attachment to the one you can’t forget.
Spending time with your current partner—who’s the complete opposite type—only makes the quiet ache of your feelings for the former one smolder in the back of your heart.
Released as the album reached a peak position of No.
5 on the Oricon charts, the track’s music video also drew significant attention.
It’s a song that will deeply resonate with anyone who thought they’d stepped into a new love but still finds themselves tethered to the past, or who has felt a rush of complicated emotions upon seeing an ex looking happy.

For anyone burdened by the agony of loving someone too much, a mix of dependence and longing, this track will surely strike a chord.
Masanori Shimada’s arrangement, with piano and guitar intertwining, makes the poignancy all the more vivid.

Though she still has feelings, the protagonist’s struggle to choose a clean break in order to move forward is deeply affecting.
Positioned as a side story to “Betsu no Hito no Kanojo ni Natta yo,” a one-take recording was also released in 2020.
It’s a must-listen for anyone who’s gone from mutual love to one-sided, or who wants to move on but can’t quite bring themselves to do it.

Dried flowersYuuri

Many people probably find breakup songs emotional.
There are countless breakup songs with aching melodies and tear-jerking lyrics that hit hard even if you’re not heartbroken right now.
“Dry Flower,” sung by singer-songwriter Yuuri, is one of those emotional, moving breakup songs.
