After spending some time together, Lex felt like he had developed a bit of friendship with the group of three. But with the addition of Sohee, Kenta's new wife, the group became extremely awkward and silent.
Any time Kenta would try to talk to Sohee, or even talk at all, she would say something that would shut him up. She would say things like, 'if I had to be replaced by someone, I at least hoped it was someone competent,' or 'I'm glad to see that even after getting married you can be such good friends with the princess you were caught flirting with'. Honestly, Lex had no idea how he could remedy the situation.
Although he tried a few times to smooth things over, it seemed like Sohee was just in a very bad mood right now - not that Lex could blame her.
