Slowly developing relationship in both dramas. Male leads appear cold but have a warmer side in them. Both dramas give off kind of slice-of-life feeling.

Both dramas have male leads who own a company and are arrogant and stoic but the female lead reveals a new side of them. Female leads in both dramas are no pushovers although in 'I hear you' the female lead is not as aggressive as in 'About is Love'.

Both are very well made lakorns revolving around big families...the atmosphere is very different but both are enjoyable.

although WWWY is more high school centred and PYHOMS is more college-ish centred both dramas have a smart male lead that does pretty well in school. In both the dramas the female lead has a childhood friend and in which the male lead also comes into the picture which causes a love triangle between the three of them. Both dramas also have friend group that goes out and hangs out together and both shows also portray the school/college life pretty well.

Somehow these 2 drama has that same emotional feeling when you watch them. Main male lead enters different parallel universe that leads him to encounter the female lead by accident. Male tries hard to change female leads outcome in the future and protects her from any possible death that may occur. Female lead tries hard to hide her feelings from male lead due to confusion in their starting relationship. Male lead tries hard to make female lead recall of the past before he runs out of time to be with her. Both has sad ending, not a happily ever after love story and seems to have continuing seasons that connects more stories.

The main male lead came from another dimension and met the female lead on earth falling in love with her. He spends his many lifetime of years on earth looking for the reincarnation of the female lead. The female lead are both popular/celebrities in the final cycle of life and did not recognize the male lead. The male lead love the female lead so much that he protected her with his life and has pure love for her every past lifetime that he met her

Both female leads know more about the male leads than the male leads are aware.
It has so many similarities, apart from the fact that in My Mister we have someone quite broken whereas in Big Issue our female lead managed to rise form that and became someone quite strong.

1: fBoth drama are written by the same screenwriter '
Apart from the fact that one is build around politicians and their secrets, and the other about paparazzis and the things they discover, both dramas are extremely similar. From the character similarity of our male leads are nearly identical, both have a trauma from their past and both are at the bottom. Both meet women with a near identical character, and both women play an equal important part. although in Big Issue it is slightly more.
Definitely give the other a try if you like one of them.

Both deal with corruption with higher ups and revealing a big secret/overall theme. Leads are kind of similar with fiery-ness but both dedicated to the cause.
