Reversed lovers

The atmosphere in the house is tense. 

Minami Sei is glaring at Choi Minho who wouldn't look at him. Sitting beside Minami Sei, Wakana is fidgeting, eyes darting between Choi Minho and Minami Sei. Natsumi squints her eyes on her sister's stalker and lastly, Sayuri is wrecking her brain on how to stop a war breakout. 

"I will read your fortune first," Oh Soo-Mi says to Minami Sei, breaking the tense silence.

"No need," Minami Sei tells her with a grave voice.

"A three-card spread is quick and…" She places the cards on the floor, slowly picking three cards from the spread. Wakana notices that the cards are completely black. It's different from the time when Oh Soo-Mi made readings for her.

"Ah…" Wakana blinks her eyes. "Oh-san, you can speak Japanese." 

"Minho taught me," Oh Soo-Mi replies quietly.
