OgCale is definitely the type of person to willingly and enthusiastically join into strangers' acted lies.
Little kid pretending to be waiting for her sibling? Yeah, he's the sibling. Cale Henituse who? He's this kid's older brother. Back off.
Guy pretending he has to go, really, he can't stay chatting, to get away from someone who won't take no as an answer? "Dad, can we hurry up? I'm not feeling well—"
Obviously uncomfortable teenager saying "I'm not allowed to date" to reject someone who scares them? He's their bossy cousin who will totally rat them out to their parents if they dare to take longer than that to talk. He makes sure to look extra mafia-worthy.
Some person getting cornered to go somewhere alone? He's their overprotective best friend. Where do you think you're taking them without him?
Rok Soo's friend says he's already seeing someone to avoid a malicious arranged marriage/set up partner by his evil step-mother? "Dear? What are you doing here? I thought you had something to do today". Suddenly, he's Alberu's secret boyfriend from many months. They met through a friend in common, Alberu asked him out first but OgCale confessed first, they do stuff like playing strategy games together, baking (Alberu bakes, OgCale tastes), enjoying music (OgCale plays, Alberu likes to listen to him) and going on walks. Obviously, a supportive model boyfriend like Alberu wouldn't even consider meeting anyone else while already having a partner himself.
Alberu doesn't know whether he should be impressed or alarmed that one of Rok Soo's friends he barely knows beyond his name somehow managed to keep an hour long conversation based on credible lies about Alberu himself. But at least it worked and he only asked for a dessert in exchange.
