like the feeling you get after finishing weight lifting and strong woman do bong soon and goblin? I haven't watched a drama in a while because I can't seem to find one that isn't sad or has a bad ending or bad romance. Any suggestions?

If you want Goblin feels, Chicago Typewriter is for you. OSTs, romance and feels are so similar. Actually the story is better than Goblin. You should give it a chance.
It's okay , it's love ..... I am currently watching , I found myself smiling involuntary like an idiot ???????????? totally recommend 
Love O2O was the first thing that came to my mind
@ serin Chicago Typewriter has a sad ending though... 
@ Hanah Love O20 was okay but bored me to tears...

Oh My Venus  (it has a blip of sadness but not for long)
i know that feeling! it's me when i watched It's Okay That's Love..it's like a roller coaster journey.
Murphy's Law of Love - This drama kept the drama pretty much at a minimum and didn't really have much conflict that left me sad.
Oh My Venus
