Spoilersssss
In the raws Sooyoung got beat really bad and then Minhyuk came and killed the gangsters who did it. After that, he took Sooyoung somewhere and took a shower. When Sooyoung woke up he kept saying he needed to go, but Minhyuk was holding him down so he wouldn't get up bcs he needs to rest. Sooyoung noticed that Minhyuk's arm was bleeding and he was surprised that Sooyoung was worried about him when he's the one who got beat up very bad. Then Minhyuk drank some medicine and fed it to Sooyoung (so it was like a kiss) End of the chapter.
