Gumi is a gardener/Vocaloid trying to come to terms with a divorce that happened between her and her ex-wife. The two met because the woman loved Gumi's garden, but a few mistakes and miscommunication gone wrong caused the two to break up.
Gumi expresses a very strong desire to reunite with her wife again, but at the same time, she also feels upset and angry, as expressed by the line, "when I bloom, it won't be for you". Perhaps these words of defiance is a plead for her ex to notice her.
