EVIDENCES THAT JUNG HWAN IS THE HUSBAND
1. The future husband speaks in low-tone, and a bit grumpy, at one point asked his wife "Do you want to die?" totally Jung Hwan's personality
2. Girls from Reply series always end up marrying the guy who always bickers with them. Jung Hwan bickers with Deok Sun the most
3. his strong denial when his friends said Deok Sun is cute. This could be a huge slap when he's indeed falling for her
4. He called her "ugly", while she called him "Dog" giving each other's nicknames already looks close to me..
5. his subtle smile when others applauding Deok Sun's performance on TV. Look at that smile! he's clearly proud of her!
6. The way future Deok Sun talks to her husband. It's more bickering than lovey dovey.. even hitting her husband. she only talks back like that and hit like that to one person: Jung Hwan
