Vol 3: Ch 139 - *A day before visiting her hometown*
The couple sleeps late for two days because they're still watching the Korean Drama which is Secret Garden. Right now, few episodes before it ends, the couple pauses the drama for a while and focuses their attention on them as they're chatting to each other.
"Tae, tomorrow I will be leaving but don't worry I will return soon, that's my promise, okay?"
"Yeah, I know, and be careful"
"As always"
Then Tae stares at her and looking at her seriously before cupping her face and then slowly approaching her before giving a passionate kiss.
For the first time, Tae entered his tongue to her and slowly testing her mouth meanwhile, when Rei feels his tongue getting inside her mouth and also feel the touch of his tongue to her, at first she's so dumbfounded and shocked but then slowly and slowly she responded to his advances.
