@dotawolfbrother simple as it look. There can be a lot more detail to explode. Not sure where to start.
Facial! the expression of this feel flat to me. I find it draw quite stereotype. Most is just overuse red line of blush.
It also depend on a lot of dialog. The guy have crush on the girl: origin flash black with explanation of a lot of text. Girl said "get to hug person you love" in the right time for the guy to understand. All that just boring.
"A picture is worth a thousand words". For the comparison, there also a hug, from ch 6
notice the guy face. It change from a surprise of a suddenly event. Then he realize it and finally, reaction. in the contract, this have only one panel, and the guy didn't show any reaction after the doubt is clear when she reveal that she love him and explain the cause of all this. one another thing is that in ch6, you have the fully introduce of the character in just one very first panel. By that, it can save a lot of space for better use. Now try read it again, they have the same amount of panel but ch6 feel a lot longer since there are a lot more thing happen. Guy see girlfriend gaze at him, hide his face. Then try another move as he realize she Mimic him. Then when guy thought about next move he would pull, girlfriend did it first. Guys surprise but did the same, and then a surprise hug. i rest my case
