Nadeshiko Sangatsu's Manga List

On a whim, Shina decides to paint his nails with his sister's nail polish. Seeing the beautiful sky-blue color on his nails makes his heart pound, but he's worried that it's weird how into his sister's stuff he is... so, he confides in his classmate, Shibuya.
After talking to Shina, Shibuya developed an interest in cross-dressing videos. Confused by their feelings, the two boys find themselves painted in sky-blue confusion in a rose-colored romance.

Akira is a popular novelist with amnesia. The man who has been caring for him since he woke up in the hospital, Yukiya, is not actually his younger brother at all...?!
On top of that, ever since the accident, Akira has been having vivid dreams of him and Yukiya doing far more than just kissing. What does it all mean? Why is Yukiya really by his side?

As Akira's suspicions grow, he begins investigating their relationship. Eventually, Yukiya reveals the truth to him:
"The first one to lie was you, Akira."
