It’s a mutual-love song that makes your heart flutter, capturing the restless feelings from a male perspective and the slightly awkward vibe of a new relationship.

Eine KleineYonezu Kenshi
Just because two people are in love doesn’t mean everything will go smoothly.
We get scared of changing feelings, and we overthink and get anxious.
For moments like that, there’s a perfectly fitting, sentimental love song: Kenshi Yonezu’s “Eine Kleine.” Even though thinking about the person you love should make you happy, it’s easy to fall into negative thoughts—everyone does sometimes.
It’s a slightly sad, heartrending love song about wishing for that person’s happiness while putting a lid on your own feelings.
