This is retarded. It's not like dumbass Shouma into REAL grade schoolers cause he was ok with her being 1st year HS girl. So why is the problem with 3rd year then, especially now when they are pretty close? It's only 2 years difference and she looks and speaks like small girl, not to mention she was able to act like some shy child perfectly.
Imagine be lolicon and reject passionate, super cute, legal (and rich) loli. Later he will regret this for the rest of his life
