An alternative scenario to this would be the seme having the jinx but the uke somehow convinces him that maintaining a healthy routine is more secure to get a win then his jinx, through the matches and Kim Dan could also be there for the seme when he was going through that losing weight or getting hit in the middle of the match stuff. And they could slowly bond like that. Focusing more on the boxing stuff than the sex and smut and porn. EVEN IF THE DELIVERY WASNT GOOD IT WOULD BE A FIVE STAR GOLD MANGA TO REREAD ANYTIME BC OF THE DRAWING STYLE BUT NO! oh my god, JK raped Kim Dan. Wow. So hot. So sexy. It's ok bc he is so handsome. Wow. Rape. So romantic. Wow. Fountain sex scene. So horny. Omg. This author really knows how to make good bl, huh? One last time. Wow.
AND, AND, KIM DAN FALLS IN LOVE. WOW.
How do you give less than one star to a manga...
