Honestly, it's not that bad.
There are a few mistakes in grammar but you can still read the story regardless. It is a bit off-putting at times, but it is what it is.
The way the MC reacts after being betrayed is questionable, but it makes the story move faster so it's not a big deal. Although the ML's actions are highly erratic, who even brings a person they just met into their house or office?
Usually, these bosses will just call their subordinates and make them deal with the situation. It is a bit forced but it helps the story develop, so there's not much I can say.
Overall, it was a good read. Keep it up!
