"A Flower Garden in the Mind" is a song from Armour Eternal. It is sung by Fish Eye.
"Nounai Ohanabatake" is a Japanese idiomatic expression that refers to someone a bit shallow and out of touch with reality; that they've got flowers on the mind rather than anything substantial. Fish Eye has failed to understand this and sings this song without irony as some sort of romantic imagery.

待ちわびていたの運命の出会い (such lonely days)
日々を自分磨きに当てたわ
努力の種蒔いた分だけ
報われる今ならあなたの一輪のバラになれるわ（ちょっぴりトゲがあるけど）
「いやーん！」
特技はカワイイ子であること好きな人に尽くすこと
Machiwabiteita no Unmei no Deai (such lonely days).
Hibi wo Jibunmigaki ni Ateta wa.
Doryoku no Tane wa Maita Bundake Mukuwareru.
Ima Nara Anata no Ichirin no Bara ni Nareru wa (Choppiri Toge ga aru Kedo)
“Iyaan!”
Tokugi wa Kawaii ko de Aru Koto Suki na Hito ni Tsukusu Koto.
