Comment by Applepi on I Like Your Pheromones - Chapter 19

@Applepi in the earlier chapter he jiayan told xingci he would call him 'dad' with respect after making his younger brother stop crying

@ivansdih  aah ty, i read further and it made more sense

@Applepi It is common to call another man you respect "dad" in China. I can mistaken but I already saw that in other chineesse stories like Nan Hao and Chang Feng
