Absolute relationshipakai kouen

I’m totally drawn in by the distorted guitar sound! This is a piece by the girls’ rock band Akai Ko-en, released in 2014 as their fourth single.
It was used as the theme song for the drama “Lost Days.” The riff, melody, and overall tone have an avant-garde vibe—seriously cool! And the title “Zettaiteki na Kankei” (“Absolute Relationship”)… when you look at it together with the lyrics, you can sense something ominous brewing.
Songs about “forbidden love” are often on the mellow side, but if you’re looking for something a little different, definitely give this a listen.

lover; mistress; extramarital partnerTeresa Ten

This song, titled “Aijin” (Lover/Mistress), could be said to epitomize infidelity both in its title and its lyrics.
Released by Teresa Teng in 1985, its words evoke not today’s affairs so much as the older image of a mistress, portraying a steadfast, strong woman living in the shadows.
Even after Teresa Teng’s passing, many singers have covered the song.
My pager doesn’t beep anymoreKunitake Mari

Pokebell ga Naranakute (My Pager Doesn’t Ring) is a song by Mari Kunitake released in 1993.
It also served as the theme song for a drama of the same title about an affair, and the lyrics express the heroine Ikumi’s feelings for Mizutani.
Even if it’s a love that only brings pain, she wants to be together and stay in love.
It’s a very heartrending song that captures a woman’s pure emotions.
The days spent just waiting for a message from the other person are truly hard.
HOWEVERGLAY

GLAY’s “HOWEVER” is a masterpiece that carries the heartfelt sentiments of TAKURO, who wrote both the lyrics and music, singing of themes of yearning and renewal.
While lamenting how late the two lovers met, it conveys a strength and tenderness that makes them treasure the present all the more—moving the listener deeply.
Released in November 2000, it also drew attention as the ending theme for the drama “Ryakudatsuai: Abunai Onna” (“Stolen Love: Dangerous Woman”).
It’s a song that gently stays by the side of those who can’t move forward while holding deep feelings for someone they love.
If you’re suffering in love, it will surely soothe your heart.
Muddy WaterSaitō Kazuyoshi

It’s “Muddy Water,” the theme song for the 2016 version of the drama Unhappy Fruit.
The same drama was also broadcast in 1997 with a different cast.
The song gives the impression of someone thinking, “Why is it only me…?”—worn out by a love with no end in sight, and nostalgic for their former self who had no doubts.
TABOOKōda Kumi

True to Kumi Koda’s style, the danceable and cool track “TABOO” is her 41st single, released in 2008.
While it doesn’t explicitly depict an affair, it feels like a song about a “forbidden love” that will resonate with anyone who’s in one or on the verge of crossing that line.
Songs about affairs that express a woman’s feelings are often sad and heartrending, but this one is something you can listen to and think, “Wow, that’s cool.”

Many listeners can’t help but relate to the lyrics, which explore a message about the beauty within women.
Released in August 2010, the song also drew attention for being used as an insert track in the drama Unubore Deka, in which Mika Nakashima herself appeared.
It went on to top USEN’s overall J-POP request chart for six consecutive weeks.
It’s a song you’ll want to hear when you wish to reflect on yourself or cherish inner beauty.
