Could someone give me a brief sumary please because im too stupid.

So the MC really doesn't want to inherit the family work, but he 'has' to so he does. He has certain feelings toward the ML that would be against how he, the successor, supposed to like-like. So they go tease each other and stuff, not sure what relationship they had. But one day the city they liven was either bomb, or got in a fire, or got an earthquake. During that terrible accident they MC finally accept that he likes the ML and they kind of get together. That;s about all I understand from looking at the raw. If someone had a better understanding please comment and tells us.

Thank you so much for this explanation.
