chan sees himself in jeongin. he sees jeongin as the chan from early trainee days. he always makes sure jeongin is okay and doing his best. because that way, not only will he help his dear brother, but also himselft from 7 years ago.
do you think Chan a year ago would have believed it if you told him that in a years time he would have debuted, and had two successful comebacks, with the nine trainees he chose himself? having traveled to so many countries and already having such a big fan base, I wonder if Chan then could have imagined such a thing happening within a year of their debut
