Next 2-3 chapters pretty sure they go home by car and xinlu starts sulking because yuri was upset at his behavior (yuri even needed to buckle/unbuckle his seatbelt for him TAT) he starts to apologize to yuri and reflects on his behavior. this is such a jump from the beginning of the novel/manhwa, as in the beginning xinlu was an uncontrollable person and tends to lash out without thinking for others and neither thinks about the consenquences. now under yuri's care (?) he grows more mature. yuri, in my opinion, is so selfless as he was willing to face xinlu head on when his temper was off the radar and was willing to take on xinlu's emotional trauma.
