素直になれない ツンデレの最終回 混ぜて焼いたケーキはもう 誰も食べずに溶けていく Bitch na Inanesama
素直になれない ツンデレのレシピ 混ぜて焼いても やっぱりビターな味がした
Iya yo iya yo mo suki no uchi? Chigau no, hontou wa... It sounds like you're looking for the lyrics
可愛いだけじゃ 物足りないんでしょ？ もう、お手上げかな だって、そういう性（さが）だし
Sunao ni narenai TSUN-DERE no RESHIPI Mazete yaite mo Yappari BITAA na aji ga shita Chigau no, hontou wa
Sunao ni narenai TSUN-DERE no saishuukai Mazete yaita KEEKI wa mou Dare mo tabezu ni toketeiku The song is about a "Tsundere" (a character who acts cold/hostile but is actually warm inside) who refers to herself sarcastically as a "Bitch" (loose translation of Bitch na Inanesama – "Lady Inane the Bitch" or "Bitchy Lady Inane"). She struggles to be honest about her feelings, hides behind provocative words, and feels exhausted from playing mind games. She wants to be understood but can't help being sour/bitter instead of sweet. The cake metaphor at the end represents her failed attempts at love – it melts away uneaten.
素直になれない ツンデレの限界 どんなに甘く盛っても どこかほろ苦いエンドロール
