You might have to reconsider your statement later on the nice personality part....

Well soon it's going to escalate into a full on toxic relationship. MC will be mostly well behaved according to ML's taste.
The turning point will be when one of ML's cousin(who was in love with ML 🤮) deliberately finds MC and insults him in his workplace. MC hides it from ML. When ML gets to know about it from his friend, he takes no action.

One month before the contract ends MC realises that he loves ML, when he asks what will happen after the contract ends, ML is ambiguous and tells that he will buy MC an apartment and they can continue the (sexual) relationship. MC realises that ML never loved him and wants to leave but ML traps him, they had pretty intense physical fight, blackmails MC with the child. One of the fights leaves MC in a broken physical and mental state and he stops eating, laughing, talking. 

Few days later when ML's friends visit him, MC finally escapes with their help and ML realises that he can no longer bind MC, so he let's him go.(This whole part constitutes 80% of the storyline)

Now coming to the final 20% :
ML realises that he too loved MC and wants to get him back and goes on following the cliche getting back your love, being rejected, still pursuing and after 1-2 years of drama they again end up together.
