I'm glad that's all it was. I'm still paranoid about tragic happenings.
It's really sweet to see Meguro find someone she cares about enough to get jealous for. In the past, I think she'd convinced herself her opinion and feelings didn't matter much when it came to "love," guys, and sex. Sensei just told / advised her to sleep with whoever, with her maybe hoping one would stick with her.
I love the sound effect "fluff" on the one page.
