I went back to the chapter to check about your ideas and... You're right about the first and the last similarities with "Private scandal" and "An hour of romance"! The second one made me think of Love Gym's seme (I don't remember his name, but he's a young blond kind rich guy)
oh! nice pick. i still have someone at the back of my head but i never care much when it comes to 'the rich blonde dude always wearing suit and beind ceo or whatnot' lol. even carried out an investigation on the topic, but found nothing satisfying enough. i thought i was having fun on my own in this guessing game, nice to have company.

am i the only one who thought she's talking about cornetto in tgcf donghua, the obsessive top looks just like kyle from private scandal and 3rd dude might be dojin from an hour of romance? 2nd guy reminds me of 2 tops but i don't remember their names and since i didn't like them that much lol
