Fretting about Someone"

 Tae-o and Song-i apologize to each other after he admits he was hurt that she did not tell him about her problems. Tae-o is still indecisive about allowing Hun and Ga-rin to live with him, but states that it's different with Song-i. Meanwhile, Song-i begins to suspect that she may have feelings for Do-hyeon. Tae-o later mentions to Do-hyeon that he wishes Song-i would find a boyfriend, as he cannot always be there for her, especially since he is planning to pursue a relationship with Se-hyeon. Do-hyeon and Song-i have a private lunch together. Hun brings Ga-rin to work with him, as an extra. She decides to learn decision-making skills from Hun after he is berated by his boss. Song-i (still unaware of her connection to Tae-o) runs into Se-hyeon during a group project, and learns that she is not into committed relationships, and thus, may have multi boyfriends. Meanwhile, Tae-o has dinner with his parents, and his stepmother gossips Song-i's mother abandoning her family and possibly having a new boyfriend. Tae-o warns his parents not to talk about it in front of Song-i. When Tae-o arrives back home, he overhears Song-i on the phone admitting that she may have a crush on someone (referring to Do-hyeon) but Tae-o assumes she is talking about him. Before he can leave, Song-i discovers him nearby and then awkwardly asks if he happened to “hear everything?”
