Koi dano Ai dano
*School Romance with smart heroine *Plain female MC, popular male MC Female MC is really smart but so oblivious of her childhood friend's feeling towards her. -One of my favorite shoujo manga. I really love how the MC is so smart and how she carefully strategize everything to be in favor of her goals. I also love how dense she is towards her childhood friend's feelings for her. Both MC's are smart - actually, most characters on this manga are smart. I even consider it as josei if not only for the school setting, yes, it's a shoujo manga that even a twenty something myself had enjoyed reading. :) HIGHLY RECOMMENDED!

*One shot *Unrequited Female MC was fond of observing the male MC back in middle school for she perceive him as someone mature only to find out at the end of the school year that he's stubborn like a child. Their path cross again at a goukon in HS and found out that the guy likes her brother's girlfriend. As they always ride the same train from school, they ended somehow friendly with each other and the female MC confess to the guy later on just to questioned if she's really sure with her feelings for they just met not too long ago and they are not exactly friends in middle school. Female MC also doubted her feelings and to make up to the 'false confession', she planned on making a way for the male MC to have a chance on her brother's gf. As this goes on, found out that her feelings for him is valid but won't confess for she's afraid this will end their good relationship as friends.... and yes it ended that way.. they may get along but the end is really a cliffhanger! i want more of this!
