1. "Perhaps Love" (CHEEZE and Eric Nam)

"Perhaps Love," originally popularized by Howl & J, first gave us that romantic excitement in 2006 when it became the main theme of the romantic-comedy series "Princess Hours." Then, in 2017, CHEEZE and Eric Nam revived it through a duet and boy did it make us all have butterflies in the stomach all over again. 

2. "LOVE" (Ailee and EXO's Chen)

The song is part of the track list of Ailee's latest album "butterFLY." The songstress announced, prior to her official comeback, that she was teaming up with the EXO's main vocalist. Both are widely-recognized as vocal legends in and out of their homeland, which made the fans already calling the song "legendary" even before the album came out. And just as how dreamy the album cover and gallery are, Ailee and Chen's "LOVE" is nothing short of pure delight.

3. "The Space Between" (Soyou and Urban Zakapa)

Can you believe that this romantic song is already five years old? Dropped in September of 2014, the now-ex member of SISTAR flaunted her singing prowess alongside the equally golden vocals of Park Yong In and Kwon Soon Il of Urban Zakapa in this track that details the budding romance between two people who seem to be afraid to plunge into love and make the first move. We call that the drumroll moment, too.

4. "Let Me Love You" (Junggigo and EXO's Chanyeol)

Released in 2017, "Let Me Love You" is the song that you want to live in, although not really because of the amusing yet really adorable music video. Junggigo and Chanyeol's voice really blended in this track, plus this is among the infrequent moments that we see this mushy side of the EXO's main rapper. With the chill beats and light piano in the background, you can't help but be smitten by the lyrics, "When you open your eyes in the morning, I'll be next to you. On sleepless nights, I'll hold you tight. Just let me love you"

5. "Ordinary Love" (Park Kyung and Park Boram)

We do feel soft when we hear this collaborative love song, despite its heavy beats and bass. It's uplifting and you feel good somehow as the lyrics narrate the budding romance between two people, while both of them are still processing what moves to do next and also assessing what they truly feel. Granting that in some cases love does not really last, the singers are both confused as their feelings grow each day instead.
