Description:

Being the first female student council president isn't easy, especially when your school just transitioned from an all boys high school to a co-ed one. Aptly nicknamed "Demon President" by the boys for her strict disciplinary style, Misaki Ayuzawa is not afraid to use her mastery of Aikido techniques to cast judgment onto the hordes of misbehaving boys and defend the girls at Seika High School. Yet even the perfect Ayuzawa has an embarrassing secret—she works part-time as a maid at a maid café to help her struggling family pay the bills. She has managed to keep her job hidden from her fellow students and maintained her flawless image as a stellar student until one day, Takumi Usui, the most popular boy in school, walks into the maid café. He could destroy her reputation with her secret... or he could twist the student council president around his little finger and use her secret as an opportunity to get closer to her.

Now that the Cards are set free, they pose a grave danger upon the world, and it is up to Sakura to prevent the Cards from causing a catastrophe! Appointing Sakura the title of "the Cardcaptor" and granting her the Sealed Key, Keroberos tasks her with finding and recapturing all the Cards. Alongside her best friend Tomoyo Daidouji, and with Kero-chan's guidance, Sakura must learn to balance her new secret duty with the everyday troubles of a young girl involving love, family, and school, all while she takes flight on her magical adventures as Sakura the Cardcaptor.

Mei Tachibana was once a regular girl who enjoyed hanging out with her friends. But after a traumatic incident where all her so-called friends suddenly turned their backs on her, Mei's idea of friendship changed forever. In order to stop herself from ever going through the same awful experience again, she decides to stay away from people as much as possible, and ideally, to never make any friends ever again. This tactic seems to have worked relatively well in her current high school life, and she didn't at all mind being thought of as gloomy and strange. However, the appearance of Yamato Kurosawa—one of the most popular boys in her high school—shakes her stable foundation of an introvert, and makes her question whether or not her choices were indeed the right ones. Not only does Yamato not ignore her like everyone else seems to be doing, he also decides to freely give her his phone number! As their relationship slowly develops, and is marked with an unexpected kiss, Mei is finding it very hard to adapt to this new life style, and hardest of all, to express her true feelings towards Yamato. Sukitte Ii na yo. follows their developing relationship, as well as their frequent disagreements, to portray how difficult it can really be to say "I love you."
