Giri Choko Girai no Futari

Overview

You realize that these aren't just obligatory chocolates, right? Obligatory chocolate is the kind that you give to people you don't even like, just because it's a Valentine's Day tradition. Aya, a beautiful office lady who is often misunderstood because of her lack of visible emotions, was complaining about it to her boss Takaki, as they walked to the train station together after work. However, Takaki told her, "That's too bad, because I was really looking forward to getting chocolates from Aya, even if it's just obligatory…" As they parted ways, Aya hands Takaki a box of chocolates. Takaki is confused, because he thought she didn't like giving out obligatory chocolates… "Senpai, are you really that dumb?" Winner of the 3rd Toaru Nichijou Manga Award, it's a sweet romantic comedy that will satisfy your heart and your sweet tooth! (Source: Kadokawa, translated)
