This is a drama I watched a long time ago, but I can't remember the name. I hope someone can help me find it. Here are the plot details:
The male lead is a CEO and also a fashion designer (something like that) at a company called Phoenix, I think.
The female lead is a manager and trainer of idols and actors.
I remember that at the beginning of the drama, the male lead rented a house from the female lead. Later, the female lead’s current residence had an issue, so she wanted to take back the house she had rented to the male lead. However, since there was already a signed contract, they ended up living together.
The reason the male lead didn’t want to move out was because this house used to be where he lived with his ex-girlfriend, who was believed to be dead. But actually, she had faked her death to go abroad for treatment.
There was a clause in the contract that whoever developed feelings for the other had to move out. After some time living together, the male lead admitted he had feelings for the female lead and silently left the house.
