With who? How?
I haven't read this in ages but I recall him sleeping with the older guy, Baek Hanjun. I think after Eunho and J broke up, Eunho was devastated and got drunk at a bar and got boned by Hanjun for consolation. My recollection is very vague though.
he didn't tho? The only time they met when Eunho was an adult was when he was like 23 and he was already back with hyung and hanjun already had a lover at that point (c62)
Its Jeaha not Eunho, Eunho is the young MC. Jeaha didn't had sex with anybody after he and Eunho broke up.
I guess you're thinking about the time Hanjun talked with Jeaha on the phone and there was a guy in his bed, cuddling him. I thouth it was Eunho at first too but it wasn't. Just some random guy/Hanjuns lover :D SO don;t worry, Eunho has nothing to confess.
I wonder if Eunho will ever confess that he had sex with that other guy too...
