Do you believe that there's a red string that connects two people? People said that the string brings soulmates together. It makes them connected everywhere... anywhere. Ejo and Cai- seems to have that. No matter what life brings into their lives, they are always connected- their heart is. But everything has its limit. Too much will never be great. In life where waves and destiny makes your love vulnerable-In this reality where your reasons will never be the answer- In this world where your feelings makes you go lower... Will Cai and Ejo last forever? Or even their strong red string that once can be with them into the infinity will be broken and separates the lovers?
