Historical Cdrama where ML is funny/aloof/energetic

• The Princess Wei Young - He's upright and honourable, but also has a sense of humour and wears his heart on his sleeve (he chases the FL).
• Sound of the Desert - The ML is an energetic general who loves to tease the FL. The SML is the stoic, quiet, composed type.
• The Story of Ming Lan - The ML's step mother (matriarch of the family) makes an effort to portray the ML (who is not her biological son) as a trouble-making black sheep. After years of that treatment, the ML basically gives up, stops trying to fight that portrayal, and makes some bad choices that live up to that reputation. But he had a good heart from when he was a young boy, and the FL helps him realize that he's made some bad choices. He has an energetic nature and sense of humour throughout, and his playfulness really comes out after he falls for the FL.
• Arsenal Military Academy - In the very beginning the ML is a sad drunk. But he quickly falls for the FL and turns into a funny and energetic person who happily plays the clown or the fool to get her attention or to protect her. 
• Dreaming Back to the Qing Dynasty - The ML is friendly, earnest and energetic. His older brother (the SML) is the serious, stoic, silent and composed type. 
• Oh My General - The ML is very dramatic, energetic and funny in his own way. Definitely not stoic, silent or composed.

Currently watching Tiger and Rose but yeah the ML there is very stoic/composed

Take my recommendations above with a grain of salt, because in my view the ML in the Romance of Tiger and Rose starts out angry, stoic and composed but quickly melts and turns into a sweet and eager character with some lines and shenanigans (along with his servant) that are pretty funny after he falls for the FL. 

Thank you! 

Probably a bit older but:

It's based on a book which is why you see so many adaptations listed on the page. 

The book roughly translates to: The Smiling, Proud Wanderer

Swordsman is probably the one with the 'least serious' male lead I can think of. By episode two you'll see what I mean and you can decide if this is the type of lead for you.
