I'm a bit annoyed with the constant "I'm a guy, I have to hold back. I'm being patient." Feels guilt trippy and like...Does Megumi NOT want intimacy? She's not doing him a favor. It should be mutual attraction.
No, she's not want it at that point. She constantly said "this is too early" everytime Shun's first attempt to make a progress. She want but it will take a long long long time. Runa did a good thing to make Megumi realized.
