He is working on a birthday project for singer Jeong Se-Woon at 'Fan & Star'.

Idol fandom's playground "Fan & Star" began a special event for Jung Se-Woon on the 9th. It is a large advertising project to celebrate his birthday on the 31st.

Jeong Se-Woon's birthday project will be carried out in cooperation with fans cheering for him. Success is determined by the number of rainbow stars (points that can be collected on the site).

Participation in the event is available at the ADs section of Fan & Star's website. It is a way of donating the stars collected by fans to advertising products that they want. Stars can be obtained by doing various activities on the site or completing various missions.
