Light RomComs with Tech/IT backdrop

I enjoyed the following dramas with specifically good romance taking place in a IT or Technology backdrop - where the (usually guy) lead is either a CEO or struggling techie and how he succeeds or recovers from his downfall with help & support from his Girlfriend.

I have enjoyed Korean, Japanese, Chinese and Taiwanese dramas in this genre.

i specifically liked the Japanese -Rich Man Poor Woman where Oguri Shun Excels as the nerdy CEO and the Korean cunning single lady as these were some of the first few dramas i watched before becoming completely addicted to Dramaland.
