you guys are being too harsh on the uke tbh. put yourself in his shoes for a sec. the ghosting was a shitty thing to do but it was impulsive - his insecurity and pride overwhelmed him. his mentality was stuck on 'he'll eventually leave me so I'll leave first'. and by the end of the manga he grew/healed from the trauma. props to the seme tho, he has patience and is a romantic (unlike us cynical readers lol)
