She opened the ointment.
Yunjin scooped out a bit with her hand and started to apply the medicine to Gu Ya.
First, she smeared the ointment onto the abrasions around Gu Ya's waist. Then, Yunjin applied it over Gu Ya's shoulders and arms. When it came time to treat his arms, for convenience, Yunjin first removed Gu Ya's clothes before applying the medicine.
After she had finished applying the medicine to Gu Ya,
Yunjin took another look at Gu Ya's impressive physique.
Such a fine figure, Yunjin thought if she didn't look now, it would truly be a waste. Besides, she was helping Gu Ya to change clothes, so shouldn't she reap some benefits?
What harm was there in looking at Gu Ya a couple of times?
"Yunjin, have you finished applying the medicine?" Gu Ya asked.
Yunjin nodded, "Yes, it's done."
She returned the ointment to Gu Ya, and now the awkward part came, as she needed to help Gu Ya remove his trousers. Yunjin looked at Gu Ya somewhat embarrassedly.
What now?
