Someone please help, There's this one story I stumbled upon but cannot remember the title. Here's what I remember:

• it's an OC story 
• arranged marriage
• male lead has an ex girlfriend claiming she's pregnant, the OC was smart enough to deal with it using a DNA Test cause obviously the ex wants him back
• I think they are royalties. ( I tried looking for it in royaltyau tag but ... Haysss) 
• When I was trying to think who's the male character, I was going back and forth woth NCT and Changmin but I'm not even sure.

If you have anything similar, please do help cause I would be stuck...

( here's another one that I've been looking for)(actually I made a blog about this way back) 

• blind male, who got surgery then regained his eyesight 
• a female OC who's afraid of thunder
• thwy end up having a child, when they slept together during a storm
• they were childhood friends
