@nightcore34 I mean I thought it was obvious.
The chapter that Ru got introduced, he essentially struggle snuggled her on the spot. The word bubbles were her getting nervous and shouting wait, cause the boxes have only been showing the MC's internal thoughts.
Previous chapter she complained about him being "too passionate"
This chapter, before Tia shows up, she mentions working on the bed first, he jokes about her wanting sex and that's why she responds, "Wroooooooooong".
Now end of this chapter, Ru complains again that MC's too much, MC says he's fine with just Ru, so what do you think they're trying to make Tia do, knit a scarf?
