The lyrics is beautiful enough.
The whole atmosphere is about two lovers whose love can persist for a long time without much changes, but still there are some slight waves during the period and the girl would occasionally feel tired of contributing to the love.
From the wordings, my impression seems the girl has a deep love on the boy but the boy may probably possess another relationship, I cannot confirm if the boy ( or man this time ) has another lover or even wife, and this girl simply drops her head in loving the boy without any compensation, without any demand, but always with a hope of opening flowers.
Hope I can help you.
