But Tezuka does get teased in some fanfics even with that stern demeanor. And he furrows his brows and bears with it in his stoic way...

Her friend's is very annoying, but Sakuno annoys me because they attempt to shove her at Ryoma and I feel she is unworthy to be even considered for him (at least the way she is now). An has a great personality, but she's just not around enough. It's amazing how irrelevant the females are in the series.
