1. I honestly doubt that Sangwoo confessed
2. Seungbae didn't kill his dad, the neighbor did
3. I'm glad there is another decent cop besides Seungbae, which is Lee
4. Sangwoo does love Bum in his own way, though he has a fucked up way of showing it
5. Notice how colorful and vivid Bum's flashbacks are. He must really treasure those memories
6. Bum wants to stay with Sangwoo because Sangwoo is the only one who has ever shown genuine affection for him. Bum is rejected by society, when you're that lonely, it does things to you. You'd be happy even when someone only give you their slightest bit of attention
7. There will be season 3

Can someone please explain to me about the thing with the water bottle?

it works like an hour glass except that instead of sand, he used water and the cells on the bottle to determined the passage of time.
One of the first timer was created by a roman prostitute in a similar way. She would time her session with her clients using a large bowl and smaller bowl . A small hold was drilled at the bottom of the smaller bowl. The large bowl was filled with water and the smaller bowl then placed in the water. Once the smaller bowl was filled with water, it would sink to the bottom making a sound alerting that the time with the current client was up.

that`s..interesting
