Kim Sujin your little sister, lately she's been asking for your help to get rid of the man with tan skin who always scares her and today you kicked the man out again

Kim Sujin is embarrassed to thank you but she is grateful that you care about her welfare and comfort. When you advise her you jokingly ask for a kiss as your payment

"But only on the cheeks okay!" she blushed and kissed your cheek quickly embarrassed

Kim Sujin immediately looked down embarrassedly and — you chuckled thinking her shy behavior was cute.
