Moments you share with your significant other won't always involve butterflies and rainbows. After a couple of years, months, or even weeks, your heart may no longer race, you face might not turn as red, and you probably won't envision SM Entertainment's signature 360 degree camera effect at every hug or kiss anymore. Your partner becomes less perfect in your eyes and the amount of bickering has increased. The excitement of the "honeymoon" stage has finally died down, but has your love?

This summer, don't simply lounge around on the couch that is your relationship and get comfortable. Romance takes work and effort! In this edition of Music Therapy, we bring you Stage 3: The Comfort Zone, with a playlist of songs that will hopefully encourage you as you struggle to figure your relationship out.

-- PART I: Do you get me? --

Younha's "Password 486": At this point in your relationship, meaninglessly saying "I love you" or "I miss you" won't fly anymore, as Younha also points out by singing, "The obvious dating tricks won't work on me." If your partner still doesn't seem to understand what you particularly like, if he or she is making mistakes but not realizing how much it hurts you, maybe it's time you are more upfront about the password to your heart. Younha shares hers in her chorus:

Throughout the day tell me [about] your love four times, smile eight times, [and] kiss me six times. [This combination] is the only password that opens up [my heart]. I will make it so that no one else knows [and] so that only you can have me. You are my secret boy, boy, boy.

Jam to the aggressive yet earnest sounds of the electric guitar combined with the piano as you allow your partner a chance to get to know you and to treat you better!

-- PART II: I'm so sorry but I love you!

-- Big Bang's "Bad Boy": Maybe you're the "bad boy/girl" here, guilty of initiating most of the fights in your relationship. And just like Big Bang, you toss and turn between giving up on someone who constantly gets angry with you and holding on to that someone who you still care about. It's easy to wait around and see how things go, but you will figure things out much faster and with less pain by making a decision and actively pushing for it. Consider reflecting on your own actions, as G-Dragon himself does at first:

That night I was too harsh. I didn't know that you would actually leave. It's because the one phrase, "I'm sorry," is so hard. We fight until the end because of my personality.

As you listen to the regretful, frustrated, and sad tones of the Big Bang members, either end things with a, "Sorry, I'm a bad boy," or initiate the change in your relationship by promising to treat your boy or your "lay lay lay lay lady" right!

Additional Recommendations: Tablo - "Bad"

-- PART III: Remember LOVE! --

IU & Seulong's "Nagging": Whether you're the one who needs to forgive, or needs to be forgiven, you're still on the receiving end of hurtful words and actions. IU and Seulong, who play an upset couple, share in this experience, as one claims, "Like a 10-year-old child, you don't listen to me," and the other bawks, "I can only laugh, who is calling who a child?" But as the cheerful beat carries on, the bickering couple come to the important realization that more than pain, love should be fostered in a healthy relationship.

From one to ten, the words [I say] out of concern for you. But since you don't listen to me, it's only nagging to you. Let's stop, let's stop. There's not even enough time to just love.

H.O.T - "Candy"

[The words] 'I only love you', I told them to you like this. The many words that I've prepared [to break up with you] have reversed. 'I will always be by your side,' I guess I will make this promise as I look to the sky.
