My theory is that he will have sex before match but it would be consented sex that Dan will want. It would be the most gentle and romantic sex they will ever have. But he will not have sex before the final match because Dan's grandma would be in critical condition and Dan would need to leave but Jaekyung will win it for him.

Also theory: he might not have sex with Kim Dan before the match, since he realizes Danny is no where near ready for that
