Hmm hmm hmmm..... I also hope those three were friends and MC's dad helped her taking a good shot cause she thought he's best friend... but hmm... was it possible that MC's dad actually had feeling for her but ended up kept it a secret? Well they're in love with each other so for the sake of their relationships he prefer to stay as friend not trued to be love rival.... still it's a bit sad if he's too focus on deep sea creatures and didn't place his wife on his heart like if he did with that woman (little girl's dead mom right?)
