Hello everybody, 

I would like to watch a feel good High School Drama.

Preferebly with a nice romantic love story.

I don't care when it was released, but it should have a sub somewhere. 

Thanks alot :)

Greetings

Dave

'Monstar' and 'Reply 1997' are cute and funny :)
"Cheer up" - It's airing right now and I'm often smiling watching it. This drama makes me want to go to high school and have fun just like some of these students ^^
The only j-dramas that come to my mind are Hana Kimi, Asuko March and Ouran High School Host Club... °-°
After School: Lucky or Not 1&2 (More about friendship than love, but there's still a little love line in there somewhere)
Hana Kimi (I would recommend the japanese or the taiwanese versions over the korean one, they are more light hearted and cute)
***Highschool Love On (Insanely adorable love story and overall quite fluffy, bubbly and cute)
Itazura Na Kiss - Love In Tokyo (This is totally based around highschool love, nothing too serious, and really cute)
Nobuta Wo Produce - (Insanely funny with a really cute love story)
***Reply 1997 (a perfect mixture of slice of life, comedy, romance and friendship)
***Cheer Up  (though its currently airing but like Neylana^ said, it always puts a smile and my face, plus till now I can see the budding of an adorable love story, heartwarming friendship and the struggles of being a highschool student in the current century)



***-Highly Recommended 
I second Hana Kimi which is on your PTW list. 
I would also highly recommend Nobuta wo Produce.
Others : My Boss my Hero (on your PTW), Dragon Zakura, Gakkou no kaidan, Gokusen, Kasuka na kanojo, Mei-chan no Shitsuji, Misaki number one. Omotesando Koukou Gasshoubu, OHSHC, switch girl, Tumbling, Water boys, Yamada-kun to 7jin no majo, Yamada Taro Monogatori, Yankee-kun ot megane chan, Yowakutemo katemasu, Yukan club...
Most are funny dramas. All of them are subbed.... somewhere.
There are tons of other school dramas, some have more deep and complex stories, .
(school 2013)  is my favorite  drama but it doesn't have romance its about friendship but its really great
(boys over flower ) its cute and have romance
(heartstring) its a really good one with the romance and friendship but its collage not high school
(school 2015 ) its good and has a love triangle
(angry mom ) is a good drama focus on the problems more but it has a light romance
(high school love on ) its cute with a little but of angle become human but its good
there is also  (reply 1997 ) and (cheer up ) but its still airing  .
