A clean and friendly Japanese-style 4-panel golf manga. Comical but educational tone, suitable for adult beginners. Soft colors, clear expressions, easy-to-understand visuals. Characters wear proper golf attire. Green putting surface is clearly visible. Panel 1: ① Marking and Picking Up the Ball On a golf green, a player notices their ball is on another player's putting line. The player politely places a small round ball marker directly behind the ball and picks the ball up. Another golfer is preparing to putt. Clear putting line visible on the green. Educational and polite atmosphere. Japanese speech bubble: "Always mark and pick up your ball when it's on someone else's line." Panel 2: ② Protecting the Putting Line Two golfers standing on the green. One golfer carefully avoids stepping on the putting line and adjusts their position so their shadow does not cross the line. The putting line is highlighted visually. Warning-style but friendly expression. Japanese speech bubble: "Don't step on the line—and watch your shadow!" Panel 3: ③ What You Can Repair A golfer uses a green fork to gently repair a ball mark (pitch mark) on the green. Nearby, light spike marks are being softly smoothed. No excessive repair is shown. Correct and incorrect actions are subtly contrasted. Japanese speech bubble: "Ball marks and spike marks are OK. But over-repairing is a no-go." Panel 4: ④ Don't Damage the Green A golfer walking calmly on the green. In the background, small warning icons show prohibited actions: running, slamming a club, dragging spikes. The golfer looks composed and respectful. Japanese speech bubble: "Treat the green with care. No running, no hitting, no dragging."
