Debu to Love to Ayamachi to! - Episode 7

Yumeko is a quiet, downcast office worker, weighed down by crippling insecurities and self-loathing—until a sudden accident leaves her with amnesia…and a sparkling new personality. Her dramatic transformation baffles everyone around her, but with a new zest for life and unshakeable confidence, Yumeko is ready to tackle anything: love, work, friendship…and maybe even an attempted-murder mystery.
