This song is also relaxing but also sad. The lyrics, "Because summer will turn into fall" reminds me of leaving school because when summer comes, we leave school. It's not just school, it's losing your best friend which is sadder, because after you come back, you will just think of him/her, which is your best friend. You know in your heart that your best friends will stay in your heart, never forgeting you. That's why I think that this song is sad. It can also happen with family members. When you lose someone you love, He/She will always be in your heart. I hope this cheered you up a little if you lost someone who is your best friend or someone you loved. Even if you lost your best friend, you could also try to find someone like him/she. This is all I can type. I feel like having a heart attack. Wish me good luck I'll survive
