' Sakura, I appreciate the urgency you have to look after me, but I do not think that it's very much necessary it's only a minor wound that will heal on its own, no need for you to waste chakra healing me. ' Shino hated being fussed over, and strove to never get injured, though it happened sometimes, and the gash in his leg is proof to that.
The reason why he doesn't want to actually show her the wound, he's shy about revealing himself. Honestly he would rather simply let it heal on its own, he could even find bugs to clean out any bacteria that might invade.
“Nonsense, it won’t take that much chakra! And besides, No matter how small, any wound can become a serious one if you aren’t careful.”
Sakura wondered why Shino seemed so adamant on ignoring the wound. Perhaps he didn’t like the sight of injuries? No, she doubted that. Even if the sight of injuries bothered a ninja, she imagined that they’d grow used to it. Or, maybe it was because he wanted to finish the mission as soon as possible so they could head back to Konoha? Whatever the case may be, Sakura continued to work on the injury.
The green glow that emitted from her ungloved hand grew stronger as she continued to heal the gash in his leg. Now that she used her chakra to “disinfect” the wound, she began working to close up the injury. After a minute or two, the luminescent chakra faded away and the wound was nowhere to be seen. Slipping her gloves back on her hands, Sakura stood up.
“See? it didn’t take too long. Is your leg feeling better?”
