@adria Well this manhwa is based on a novel.
SPOILER
Zhenya will have a character development, the two of them will become soft with eachother (in their own way) but yea it will take a little. They do match eachother perfectly because Zhenya is the only one who can keep up with Teakjoo.
I can tell you a little more about it if you want.
If you want to read the novel we are on the 3rd volume right now but i'm unsure where exactly
