Seeing Yuta's growing distrust of men, Nanami promises to support him with her nurturing warmth and voluptuous, extra large breasts, helping him regain his confidence as a man. Gently whispering to him, she removes her bra to reveal her bare breasts, offering to walk beside him on a journey to improve his sexual skills and prove himself once again.
