This post is about IshRa's chemistry and hotness.
I dint catch the episode at night, downloaded and watched it.
When I was watching the game part, the goose bumps which they were having, I felt like I was also having the same.

When their hearts were beating, my heart started beating like a drum.

When they were looking at each other, I forgot to close my eye lids.

When they were feeling awkward and uneasy, I was blushing continuously.
When they in touch with each other, a cold shiver went from my top to toe.
So, the zest is...what was this? Was this hotness? What type of hotness? There were no boldness, no unnecessary touches, no strange expressions...there were only beauty in the whole scene. And that beauty gave me all those feelings above. So, is the hotness undefinable or redefined😛???
