When Maekawa flirts, Shimizu is very guarded now...
It's not only jealousy why she snapped. She is trying, not getting response.
Seeing Shimizu with new employer was only a last drop.
I just think she is not quite aware what exactly she feels, but she reacts anyway.
I see people would like the sweetest kiss coming with realization of her feelings. I expect something very passionate, in this case. Passionate kisses and hot sex, it means.
Maekawa is smoking hot, too much for romantic feelings only...
I guess I'm just a romantic and seeing as Maekawa seems to think that dating really is just about offering her body to the other person I think that a sweet but also passionate kiss for starters would show her that, yes, real love does not require hot passionate sex as a means to be expressed. Real love and feeling it can be expressed in the most simple of things like Shimizu's face beaming up whenever she spots Maekawa. Or Maekawa smiling warmly at Shimizu's retreating back. That's real romance right there. More than just exotic touches. The sweetness of those moments has more value to me than graphic sex
I'm not against your romantic preferences, don't get me wrong. You are giving those romantic vibes through your writing, and it's really sweet- I would treat you and respond on your vibrations properly, as person to person you would inspire me to be romantic to you.
But in manga, I'm not catching any romantic vibes from Maekawa. If I'm Shimizu, I would (censored word) her slamming her on some wall at their work place, and after it, when she comes to her senses I would speak with her romantically. :)
Apologizing for my expressiveness, but I don't see other way how to describe women which Maekawa's character represents in this manga. It's too much sexual tension for romantic acts at the beginning (it does not mean later she should not be treated romantically).
Shimizu must be a real master of patience, if she does not lose her nerves doing exactly what I said few lines above...
