"Is it a sea, is it a desert, is it hope, is it despair
Is it real, is it fake"
This is from J-Hope's line from Sea. The boys are asking if the desert is real or not or if it is hope or not or if it is despair or not or if it is hope or not or if it is a sea or if it is a desert. They are unsure of what this desert is. Jimin's logo on the shirt is 'REGRET'. Jimin regrets to love because he realized it was Fake Love.
Probably the desert is like love. You thought it was a really beautiful sea (love) but it is actually a (fake love) waterless desert
In Singularity it says "Spring will come someday" it means the leaves and plants will start to GROW again. It means that they will grow again and move on from fake love.
