Well, without more context, it's difficult to give a full account of the 'Excuse Me, This Is My Room' story from Toomics. However, it could potentially be a story centered around a character who has a strong attachment to their room. Maybe there are misunderstandings with other characters regarding the use of the room, and through a series of events, they learn to share or resolve the issues related to the room.
I'm sorry, but without actually having the 'Excuse me this is my room' full story, I can't summarize it. You can give me more details about the story like the main characters, the plot events etc., so that I can summarize it for you.
The interesting parts could vary. Maybe the initial encounter where the person says 'excuse me this is my room' is filled with tension. It could be that the person is facing a group of people who don't believe it's their room. Another interesting aspect might be any evidence or memories the character has to prove it's their room. It could be an old photo on the wall, a mark on the floor, or a memory of a childhood event in that room. And if there are other characters who start to side with the person claiming the room as the story progresses, that could also be an interesting development.

The reason could be anything from a romantic encounter gone wrong to a mystery that needs solving. Maybe it's part of a larger conspiracy or just a random act that leads to unexpected developments in the story.
It's hard to say. Sometimes the layout and availability of rooms can vary depending on the plot and settings of the manhwa. You'd better read it carefully to get the answer.
