Love o2o is fluffy and the lead is calm, nice and supporting.
Boss & me also a nice male lead, supporting. He can be a lilttle much sometimes, he forgets to explain or reason with the female lead.
I second The legends, is nice to watch. Even when de ML is supposed to be hard, evil and a ass* he still has that innocent flair and he will give his life for his love.
The masked lover, my favourite tiawanese drama. I liked the seconed couple. They where really all in. The guy will leave his life behind to make her happy.
Perfect couple (sec. favourite taiwanese drama)
General and I is one of my fav. chinese drama, not sure if it is what you are looking for.
All the dramas have a happy ending, i cant watch something that ends sad ;)
* At the moment go go squid is airing, i watched the first 3 ep. looks promising.
As for lakorns i find it hard to give you any. The ones i know do not fit your question 100 %. Maybe you like the ones with Mik. You can find them in my watchlist.
