Seoul during spring

Hi everyone! I’m going to Seoul April 12th and I’m counting down the days lol. I go to South Korea pretty often since my husband is there and I’m in New York. But I have never been in spring and I’m so excited! My husband lives in the Gangdong-gu area. I’m wondering does anyone know of any good spring places to visit in that area or even further? I do know the area like I visit Gyeongbokgung palace pretty often. I’m looking to see cherry blossoms lol I’m on the missing to find beautiful areas to see cherry blossoms. My husband will be working most of the time so I’ll be doing solo adventures ☺️
