W.H.Y. (2018)

Both web series are set in a guest house on jeju island. Both are rom-coms with cute friendships too.

Both set in Jeju Island where you feel warm and cozy. Both has a cozy kind of story - a simple and cute kind of Rom-Com. It also has the same kind of story of moving on in life also in love. Also finding the right one for you at the right time with enough time. Warm and Cozy is a Rom-Com drama that has a lot of funny and sweet scene too.

Similar storyline 1. Relationship problems 2. Both story happens on a trip 3. Change of feelings of main characters 4. Similar vibes 5. Love triangle

It's not really that similar in terms of themes but they both have incredibly well written characters and they handle relationships well, both friendship and romantic.

Hwang In Yeop is in both dramas Both are about romance and break ups Both have nice cinematography

Both are about friendships and romance. Each group of friends go on summer vacation, one to the beach and one to Jeju island.

Both dramas feature couples who started their romance in a guesthouse! WHY is a webdrama though Eulachacha Waikiki has funnier scenes since it's a cable drama

Nothing is much similar to it. Just want to recommend another good web drama that everyone need to watch Both dramas are kinda refreshing and for youths. It's the drama that can't dissapoint anyone
