Light romance with sweetest ML

Recommend me please romantic k or j dramas with cute male lead. He can be kind of weak or even obsessive but nothing rough toward FL. No arrogance and coldness are welcome.
I think these dramas may (or should xD) be pretty unrealistic so it's ok if a drama have some fantasy or comedy moments.

Thanks in advance!

Two dramas on Netflix might be something you are looking for-One Spring Night and Something in the Rain.  Both have the same ML-Jung Hae In.  He was a sweetie pie in both.  I liked the latter over the former. 

Touch Your Heart, the leads are sweet and the drama is really light

Thank you all, guys!

Put Your Head on My Shoulder, like seriously... Must watch

Wanted to ask if it's ok to watch if i haven't watched A love so beautiful? Are there many connections in the stories?

There's no connection. It just has the same writer.
