Specific male lead

Byung Hee and Ji Hyuk are from here

Byung Hee - free spirit, reckless, really cares for female lead and shows it

Ji Hyuk - silent-ish, strong, protective, but affectionate when accepts his feelings for female. 

Both fall first and aren't condescending or mean to  the female lead for no reason. Bonus if some type of deliquent that isn't really bad

male lead is like a mix of the two

he is reckless and protective of the fl, but he's more dangerous than eccentric. he also likes the fl but is kinda wishy-washy at first

I see why I thought the male lead would count, but nah. He's a good character but he's not free-sprited in the way Byung Hee is nor is he silent-ish/moody like Ji Hyuk. He did fall first but he played games instead of being all in since the beginning

Nope. ML is silent and protective but not affectionate. He's nice, but that's not enough. 

SML is pretty outgoing  and reckless and he does show how much he cares for the fl, but it's more in a puppy dog way and not in a heart-fluttering way

also, I tried rewatching the series and I was skipping way more than I was watching. Even though I loved it when I was younger, I wouldn't recommend it

rewatched the first ep and he's pretty taciturn but still bold in asking fl for a date from the start-ish

so far he seems similar to Ji Hyuk
