٩(๑❛ᴗ❛๑)so it seems like yuri wanted his number to have it in case, and then it came into handy when he went to eat with his BIL+sister. it also seems like he still doesn't believe teacher about the one-sided relationship, because he thinks that there's no way teacher would accidentally kiss yuri if it had never happened before (meaning yuri thinks teacher and BIL were being frisky) so he thinks his sister might have ended up in a marriage with a gay guy who doesn't actually love her
Yeahh that's makes sense... It's so hard to see sunwoo's expression, that guy is about to 'fall off the edge' and yuri keep poking his wound
Thank you v05 and sister for the translation and uploads!ヾ(☆▽☆)
Why does yuri want sunwoo's number in first place lol it's suspicious. He asked his number even before he met BIL and his noona right? Also sunwoo already told him it was one sided, so if yuri still not sure that sunwoo's words are true there's no need to bothering sunwoo anymore since he will tell him the same that it was one sided. Even in this chapter, the reason why he called sunwoo was because he is pissed and jealous with his BIL, he only wanted to annoyed him or accused him. At this point it doesn't really matter to him if his noona is cheated or not, he only wanted to be a jerk to them (BIL and Sunwoo)
