Golden Time Vol. 2 (manga)

Of Unrequited Love, A Pixie Princess, And The Robot Dance

Tada Banri has forgotten his past, but is eager to start a new life. Yanagisawa Mitsuo, on the other hand, wants to forget his past at all cost. Meanwhile, Kaga Kouko seems incapable of forgetting–she's had Mitsuo on her mind since pre-school.

After a dangerous brush with crazy cultists, Kouko tries out a new scheme on Mitsuo. Taking inspiration from her talk with Banri while they were lost in the forest, Kouko has decided on playing the aloof card. She's going to spring a "catch me if you can" act on her beloved.

Question is, how long can she stay aloof when it seems Mitsuo's developed a crush on a new arrival–the plucky and pint-sized, but always cheerful, Oka Chinami.
