There are a lot of 아니메 Mother + Son relationships I really admire. Kushina and 나루토 Uzumaki is a main one but since it already got mentioned I'll go with Delia/Hanako and Ash Ketchum/Satoshi from Pokemon. Both pairs always reminding of me and my own Mom in particular XD Inko and Izuku Midoriya do too so they are quite a close 초 !!!!
They don't have the most touching 또는 warmest sentimental kind of relationship, but 당신 can tell they both care for and 사랑 each other very much and when they're together, they're HILARIOUS <3
