The last part of the chapter... basically, as Jin-woo arrived at the hotel, he received need that Jin ho disappeared, and the master and secretary of the guild became very worried because they knew that if Jin-woo were to find him, he would definitely kill Gwang Dong-su, a member of his guild, and his kidnapper. Thomas (the master of the guild) knew for sure that the one who kidnapped Jin Ho was Gwang Dong-su, because of the incident with his brother and Jin-woo.
So the last part of the chapter is Jin-woo mad with himself because he forgot to leave one of his shadows with Jin-ho, and Thomas panicking and giving orders to find them before Jin-woo does, as he would kill Gwang Dong-su the moment he found them. Then, you see an image of Jin-ho's shadow, clearly bleeding, and Gwang Dong-su smiling with excitement.
