I was disappointed since we got robbed from the previous chapters' gayness, but seems like...

could u tell me what gayness was on the light novel in the last chapter

Do enlighten me abt this gayness

Well, there conversation went like this in the novel

HYJ: Do you remember anything else except my name and face?
SHJ: My item
HYJ: I said to lose the possessive
SHJ: It was you (basically the SHJ from before the regression confirms that it was Yoojin who was name "My item" from his contacts)

SHJ: What kind of relationship were we in?
HYJ: We recognized each other's usefulness and would exploit them under mutual agreement.
SHJ: Anything else?
HYJ: A tour guide and an irritated guest. You were the guide.
SHJ: What?
HYJ: I'm also raising your child. You came rescuing me when I was captured by a dragon, and we did something close to dance. You bet an eye and arm on me, we participated in an auction together. You were the guest, and I was the product. The eggs were half-cooked. (That time when SHJ cooked for YJ when they were in Hongkong)
SHJ: Are you saying nonsense?
HYJ: I'm telling you one hundred percent truth. Also, we caught two SS class monsters together.

Sung Hyunjae's eyes opened wide and silently laughed. Was it me, or did he look younger than normal?

SHJ: Did I tell you I fell for you?
HYJ: You also gave me roses
SHJ: When?
HYJ: When we brought down the new association building. You weren't there. I told you to come and watch, but you refused.
SHJ: That was my bad.

Well it really was not gay but still kinda fruity I say

thanks so much
