Sekaiichi Hatsukoi is such a sweet series and I'm thoroughly enjoying it so far. It's strange...I'm actually a bit surprised with feeling able to relate to bits of Kisa's persona. I've noticed that in spite of his accomplishments he seems to dismiss them and isn't as steadfast in his self assurance like many of the other characters. He doubts, questions, and second guesses himself a lot more -- especially when it comes to Yukina or the idea of being in a relationship. I'm seeing little similarities in his mannerism too. Oh, and he's a 30 year old with a baby face, like me. How amusing! Furthermore, there was the scene in the cafe -- his reaction when he realized how much younger Yukina was than him and entertaining the notion of dating a person that young... hah! Months back I had a similar reaction and can relate.
Of course, the situation is very different, even weird. I am not dating the person. We've done projects together and a part of him annoys the crap out of me. Although another small part keeps entertaining the idea of dating. Little things has led my intuition to believe he's at least entertained the same idea if not interested but may be too arrogant to admit or act on it.
Anyway, back on topic. The similarities... at times it looks as though Kisa is trying to convince himself of something he knows, in his heart, that isn't true. Whether it be beliefs about himself or his own emotions. Sure, I suppose there's a chance that I may be over analyzing this as I haven't read the manga. I just find it strange to be able to relate to a fictional character in this manner.
Nonetheless, I'm thoroughly looking forward to seeing more of the series. I'm actually even more curious now about Takano and Ritsu.
