[...Nii-san, can I keep relying on you to protect me forever?]

[Of course, I'll always protect you as your brother, leave it to me Nagisa] As I said that Nagisa my sister blushed, with her cute and rosy cheeks I was mesmerized by her beauty but I must not have this kind of feelings for her she's my sister I'll just protect her until she finds her fated partner.

[Nii-san is always reliable, thank you Nii-san for being always there for me through my ups and downs.]

At that time I didn't know how to respond properly as her brother cause she has such a precious face right now...

[Of course, I'm your Nii-san after all.]

[Right, my Nii-san is always reliable. Arigato Nii-san]... at that time I had hoped to hear another sentence like I love you from Nii-san but for now I'm contented being protected because Nii-san can always be by my side...
