The 8Th Failed Love summary:

On one ordinary night, a relationship between the two began without much thought. For Hoyeon, that's just how it was with Soobin. Despite this, as they spent more time together, he found himself growing more sincere in their relationship. But then, Soobin said to him:"Hyung, let's break up.""Alright, do what you want. No plans on giving me a reason this time, either?"This was Soobin's 7th time breaking up with him without a reason. Every other time they had met up again within a week, so Hoyeon didn't expect any different this time... But it's been two weeks and Soobin still hasn't called!! Something felt wrong.Looking back, Hoyeon's biggest mistake was that he didn't ask the reason why they had broken up the first time.
